a. Construct segmented bar graphs to display the distribution of opinion for males and for females. b. Is there an association between gender and opinion for the members of this sample? Explain your answer

Short Answer

Expert verified

Hence there is no association between gender and opinion for this sample .

Step by step solution

01

Part (a) - Step 1 : Given Information - Survey includes1152 adults and we need to calculate their percentage weightage in order to draw the bar graph .

Part (a) - Explanation : We calculate percentage weightages after which we see their affect as a gender on the given data . After calculating data we derive a conclusion.


MaleFemale
Strongly Agree76/516=14.73%
59/636=9.28%
Agree270/516=52.33%
247/636=38.84%
Neither agree nor disagree87/516=16.86%
139/636=21.86%
Disagree61/516=11.82%
184/636=28.93%
Strongly disagree22/516=4.26%
90/636=14.15%

02

Part (b) - Step 2 : Given - We now need to derive and think of the association .

Explanation : No, there is no association between gender and opinion but the data for women has wide range of dispersion . Over two-thirds of men agree or strongly agree with this statement, compared to slightly less than half of the women. The percentages who disagree or strongly disagree tell a similar story is 16%of men versus 30%of women.

Cocoa and blood flow- A study of blood flow involved27healthy people aged18to72.

Each subject consumed a cocoa beverage containing900milligrams of flavanols daily for

5days. Using a finger cuff, blood flow was measured on the first and fifth days of the

study. After5days, researchers measured what they called 鈥渟ignificant improvement鈥� in

Blood flow and the function of the cells that line the blood vessels. What a flaw in the

design of this experiment makes it impossible to say if the cocoa really caused the

improved blood flow? Explain your answer.

Can texting make you healthier? Researchers randomly assigned 700Australian adults

to either receive usual health care or usual heath care plus automated text messages with

positive messages, such as 鈥淲alking is cheap. It can be done almost anywhere. All you

need is comfortable shoes and clothing.鈥� The group that received the text messages

showed a statistically significant increase in physical activity鈥渟tatistically significant鈥� in this context?

a. The results of this study are very important.

b. The results of this study should be generalized to all people.

c. The difference in physical activity for the two groups is greater than 0.

d. The difference in physical activity for the two groups is very large.

e. The difference in physical activity for the two groups is larger than the difference

that could be expected to happen by chance alone.

Bias in a sampling method is

a. any difference between the sample result and the truth about the population.

b. the difference between the sample result and the truth about the population due to

using chance to select a sample.

c. any difference between the sample result and the truth about the population due to

practical difficulties such as contacting the subjects selected.

d. any difference between the sample result and the truth about the population that

tends to occur in the same direction whenever you use this sampling method.

e. racism or sexism on the part of those who take the sample.

High-speed Internet Laying fiber-optic cable is expensive. Cable companies want to make sure that if they extend their lines to less dense suburban or rural areas, there will be sufficient demand so the work will be cost-effective. They decide to conduct a survey to determine the proportion of households in a rural subdivision that would buy the service. They select a simple random sample of 5blocks in the subdivision and survey each family that lives on one of those blocks.

a. What is the name for this kind of sampling method?

b. Give a possible reason why the cable company chose this method.

How is your room? A hotel has 30floors with 40rooms per floor. The rooms on one side of the hotel face the water, while rooms on the other side face a golf course. There is an extra charge for the rooms with a water view. The hotel manager wants to select 120rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property.

a. Describe how to obtain a sample of 120rooms using stratified random sampling. Explain your choice of strata and why this method might be preferred to simple random sampling.

b. Describe how to obtain a sample of 120rooms using cluster sampling. Explain your choice of clusters and why this method might be preferred to simple random sampling.
