Chapter 5: Problem 12

Investigating Dates In a survey sponsored by TGI Friday's, 1000 different adult respondents were randomly selected without replacement, and each was asked if they investigate dates on social media before meeting them. Responses consist of "yes" or "no."

Short Answer

Expert verified
The survey involves 1000 randomly selected adults regarding social media investigation of dates, resulting in categorical responses of 'yes' or 'no'.

Step by step solution

01

Understand the Survey

The survey involves 1000 adult respondents who were randomly selected without replacement. Each respondent was asked if they investigate dates on social media before meeting them, with the response being either 'yes' or 'no.'
02

Identify the Type of Data

This survey collects qualitative data since the responses are categorical (either 'yes' or 'no').
03

Determine the Sample Size

The sample size is 1000 respondents, as stated in the problem.
04

Understand Random Selection

Since the 1000 respondents were randomly selected without replacement, this means each respondent was chosen in such a way that once a respondent was selected, they could not be chosen again.
05

Analyze Response Distribution

If needed, further statistical analysis, such as calculating the proportion of 'yes' and 'no' responses, can be performed to understand the trend.

Key Concepts

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

Random Selection
In the context of this survey, random selection means that each of the 1000 adult respondents was chosen without prior notice.
This ensures that every respondent has an equal chance of being selected.
It鈥檚 like drawing names out of a hat; once someone鈥檚 name is picked, it鈥檚 set aside so they can't be picked again.
This method helps to eliminate bias, making sure that the survey results are as fair and representative as possible.
Sample Size
Sample size refers to the number of individuals participating in the survey.
In this case, the sample size is 1000 adult respondents.
A larger sample size can improve the accuracy of the survey results, because it reduces the margin of error.
Think of it as having a clearer picture when more pieces of a puzzle are in place.
However, choosing a proper sample size is crucial. If the sample is too small, the results may not accurately represent the entire population.
Survey Response Distribution
Survey response distribution involves analyzing how many respondents answered 'yes' or 'no' to the survey question.
By examining this distribution, you can identify trends and patterns in how people behave.
For instance, if 600 out of 1000 respondents said 'yes,' it indicates that a significant number of individuals investigate their dates on social media.
Understanding response distribution can help in making decisions based on the survey findings.
For deeper analysis, statistical techniques can be used to calculate the proportion and compare it against various demographics or other surveys.

Most popular questions from this chapter

Assume that the Poisson distribution applies; assume that the mean number of Atlantic hurricanes in the United States is \(6.1\) peryear, as in Example 1; and proceed to find the indicated probability. Hurricanes a. Find the probability that in a year, there will be no hurricanes. b. In a 55 -year period, how many years are expected to have no hurricanes? c. How does the result from part (b) compare to the recent period of 55 years in which there were no years without any hurricanes? Does the Poisson distribution work well here?

Poisson Probability Distribution The random variable \(x\) represents the number of phone calls the author receives in a day, and it has a Poisson distribution with a mean of \(7.2\) calls. What are the possible values of \(x ?\) Is a value of \(x=2.3\) possible? Is \(x\) a discrete random variable or a continuous random variable?

Notation Assume that we want to find the probability that when five consumers are randomly selected, exactly two of them are comfortable with delivery by drones. Also assume that \(42 \%\) of consumers are comfortable with the drones (based on a Pitney Bowes survey). Identify the values of \(n, x, p\), and \(q\).

Geometric Distribution If a procedure meets all the conditions of a binomial distribution except that the number of trials is not fixed, then the geometric distribution can be used. The probability of getting the first success on the \(x\) th trial is given by \(P(x)=p(1-p)^{x-1}\), where \(p\) is the probability of success on any one trial. Subjects are randomly selected for the National Health and Nutrition Examination Survey conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. The probability that someone is a universal donor (with group \(\mathrm{O}\) and type Rh negative blood) is \(0.06 .\) Find the probability that the first subject to be a universal blood donor is the fifth person selected.

Car Fatalities The recent rate of car fatalities was 33,561 fatalities for 2969 billion miles traveled (based on data from the National Highway Traffic Safety Administration). Find the probability that for the next billion miles traveled, there will be at least one fatality. What does the result indicate about the likelihood of at least one fatality?
