In the same article from Exercise 46, Time magazine, reporting on a survey of men's attitudes, noted that "Young men are more comfortable than older men talking about their problems." The survey reported that 80 of 129 surveyed 18 - to 24 -year-old men and 98 of 18425 - to 34-year-old men said they were comfortable. What do you think? Is Time's interpretation justified by these numbers?

Short Answer

Expert verified
After calculating the percentages, whether Time's interpretation is justified is determined by comparing the percentages. If the percentage of 18-24-year-olds comfortable talking about their problems is higher, then Time's interpretation is valid.

Step by step solution

01

Calculate Percentages

Begin by calculating the percentage of men from each age group that reported being comfortable talking about their issues. To do this, divide the number of men 'comfortable' by the total number surveyed in each group and multiply by 100. Use the formula: \(Percentage = \frac{Number \, of \, Comfortable \, Men}{Total \, Number \, Surveyed} \times 100\). Calculate for both age groups.
02

Calculate for 18-24 group

Apply the formula for the 18-24 age group: \(Percentage = \frac{80}{129} \times 100\).
03

Calculate for 25-34 group

Also, apply the formula for the 25-34 age group: \(Percentage = \frac{98}{184} \times 100\).
04

Compare Results

Now that comparisons are available, they can be used to determine whether Time's interpretation was justified. If a higher percentage is found within the 18-24 age group, then the interpretation is correct.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Survey Data Analysis
Survey data analysis is a powerful tool for understanding demographics and behaviors within a population. When Time magazine reported on men's attitudes, they collected data by surveying different age groups of men and asked whether they were comfortable discussing their problems. A relevant step in analyzing this survey data is to ensure accurate representation and interpretation of the responses. By focusing on the proportions, rather than raw numbers, we can gain insights into the prevalence of attitudes across different cohorts.

Considering that raw data can sometimes be misleading, it's crucial to process the results statistically. This involves calculating percentages to provide a fair comparison between groups of different sizes, which is exactly what was done in the step-by-step solution. Without converting these figures to percentages, we might incorrectly weigh the opinions of the two age groups. Thus, percentages illuminate trends in data that could otherwise be obscured by the sheer volume of responses or the variations in group sizes.
Percentages Calculation
Percentages calculation is a fundamental aspect of survey data analysis, as it allows us to standardize data for comparison. The step-by-step solution provided uses a simple yet effective method to compute these percentages by allocating the specific number of affirmations to the total number of individuals surveyed within each age group.

In our example, the formula \(Percentage = \frac{Number \, of \, Comfortable \, Men}{Total \, Number \, Surveyed} \times 100\) converts the raw numbers into a relative form which accurately represents the behavior of each group regardless of its size. Consequently, this method also amplifies the interpretability of the dataset, allowing us to understand the proportion of respondents who share a particular viewpoint. Moreover, when we communicate this data, percentages are much easier for others to grasp as they offer a direct way to gauge frequencies or ratios in a standard 'per hundred' format.
Age Group Comparison
Comparing age groups is essential when interpreting survey results, particularly when the survey's aim is to highlight differences or similarities between demographic segments. Time magazine's statement about young men being more comfortable discussing their problems than older men hinges upon this demographic comparison.

Using the percentage calculations from our steps, we can objectively compare the attitudes of the two age groups of men. If the percentage is higher for the 18-24 age group, then statistically, it suggests that younger men are indeed more comfortable talking about their problems when compared to the 25-34 age group. Such comparisons can provide valuable societal insights and help debunk or reinforce common perceptions. It's imperative, however, to approach these comparisons with sensitivity to the nuances of survey design, sample size, and the respondents' diversity, as all these factors impact the reliability and generalizability of the results.

Researchers comparing the effectiveness of two pain medications randomly selected a group of patients who had been complaining of a certain kind of joint pain. They randomly divided these people into two groups, then administered the pain killers. Of the 112 people in the group who received medication A, 84 said this pain reliever was effective. Of the 108 people in the other group, 66 reported that pain reliever B was effective. a. Write a \(95 \%\) confidence interval for the percent of people who may get relief from this kind of joint pain by using medication A. Interpret your interval. b. Write a \(95 \%\) confidence interval for the percent of people who may get relief by using medication B. Interpret your interval. c. Do the intervals for \(A\) and B overlap? What do you think this means about the comparative effectiveness of these medications? d. Find a \(95 \%\) confidence interval for the difference in the proportions of people who may find these medications effective. Interpret your interval. e. Does this interval contain zero? What does that mean? f. Why do the results in parts \(c\) and e seem contradictory? If we want to compare the effectiveness of these two pain relievers, which is the correct approach? Why?

You are a consultant to the marketing department of a business preparing to launch an ad campaign for a new product. The company can afford to run ads during one TV show, and has decided not to sponsor a show with sexual content. You read the study described in Exercise 75 , then use a computer to create a confidence interval for the difference in mean number of brand names remembered between the groups watching violent shows and those watching neutral shows. TWO-SAMPLET \(95 \%\) CI FOR MUviol - MUneut : (-1.578,-0.602) a. At the meeting of the marketing staff, you have to explain what this output means. What will you say? b. What advice would you give the company about the upcoming ad campaign?

A new vaccine was recently tested to see if it could prevent the painful and recurrent ear infections that many infants suffer from. The Lancet, a medical journal, reported a study in which babies about a year old were randomly divided into two groups. One group received vaccinations; the other did not. During the following year, only 333 of 2455 vaccinated children had ear infections, compared to 499 of 2452 unvaccinated children in the control group. a. Are the conditions for inference satisfied? b. Find a \(95 \%\) confidence interval for the difference in rates of ear infection. c. Use your confidence interval to explain whether you think the vaccine is effective.

The Core Plus Mathematics Project (CPMP) is an innovative approach to teaching Mathematics that engages students in group investigations and mathematical modeling. After field tests in 36 high schools over a three-year period, researchers compared the performances of CPMP students with those taught using a traditional curriculum. In one test, students had to solve applied algebra problems using calculators. Scores for 320 CPMP students were compared to those of a control group of 273 students in a traditional math program. Computer software was used to create a confidence interval for the difference in mean scores. (Journal for Research in Mathematics Education, 31, no. 3) Conf level: \(95 \%\) Variable: Mu(CPMP) - Mu(CtrI) Interval: (5.573,11.427) a. What's the margin of error for this confidence interval? b. If we had created a \(98 \% \mathrm{Cl}\), would the margin of error be larger or smaller? c. Explain what the calculated interval means in this context. d. Does this result suggest that students who learn mathematics with CPMP will have significantly higher mean scores in algebra than those in traditional programs? Explain.
