Transcribed Image Text:The American Trends Panel (ATP) is a national, probability-based online panel of adults living in households in the United States. The following data come from Wave 64
of the panel, which was conducted from March 19, 2020 to March 24, 2020. The Wave 64 survey focused on how Americans felt about and experienced the coronavirus
pandemic at that time.
The following table shows summary data for the Mental Health Index (MHI) scores for respondents, organized by political party identification. A higher score indicates
that a respondent experienced more mental health issues in the past 7 days, including anxiety, hopelessness, and trouble sleeping.

7. Respondents with MHI scores of 12 or higher are known to be at very high risk for mental health complications. Among Republicans, approximately
percent are at very high risk for mental health complications.
8. An MHI score above 7 is considered indicative of life conditions that are at least moderately stressful. Among Republicans, approximately
percent are experiencing life conditions that are at least moderately stressful.
9. We can be 99% confident that the true population mean MHI score for Republicans during this time period is between
(lower limit)
to
(upper limit).
10. Imagine that a public health organization would like to deploy a support program to populations where at least 50% of the population experiences life
conditions that are more than moderately stressful (defined as a mean MHI score of 8 or higher). Should this program be deployed to Republicans?

Owners of a children's toy store chain asked this question. Some data collected by the chain are summarized in the table below. The data were obtained from a random sample of 180 people. The birthdate of each person was recorded, and each of these dates was placed into one of four categories: winter (December 21-March 20), spring (March 21-June 20), summer (June 21-September 20), and fall (September 21-December 20). The numbers in the first row of the table are the frequencies observed in the sample for these season categories. The numbers in the second row are the expected frequencies under the assumption that birthdays are equally likely during each season of the year. The bottom row of numbers gives the following value for each of the season categories.

- Does it seem to you that people tend to be absent more on some days of the week than on others? Recently, a major biotechnology firm collected data with the hope of determining whether or not its employees were more likely to be absent on some weekdays than on others. The firm examined a random sample of 130 employee absences. The distribution of these 130 absences is shown in the table below. The observed frequency for each category (each weekday) is shown in the first row of numbers. The second row of numbers contains the frequencies expected for a sample of 130 employees if employee absences at the firm are equally likely on each of the five weekdays. The bottom row of numbers contains the following value for each of the categories.arrow_forwardDr. Sloane is doing a study to test the association between alcohol consumption and the occurrence of cancer of the liver.

He makes sure that the cases and controls are similar by age and sex. A. Looking at the odds ratios and the p-values together, describe your observations. B.

- The U.S. National Center for Health Statistics complies birth statistics and publishes the results in vital statistics of the United States. The Center has historically believed that the mean of all newborns in the U.S. has been no less than 6.95 pounds. A sample of babies is selected so that the center can revise its belief. The following birth weights, in pounds are recorded: 7.4, 6.0, 8.6, 4.5, 2.0, 7.9, 4.0, 2.6, 5.9, 7.3, 7.3, 7.0, 6.3, 8.1, 7.1, 7.3, 6.6, 5.2, 9.8, 8.0, 10.9, 6.5, 3.8, 5.0, 8.0 a). At 5% level of significance, do these data provide sufficient evidence to refute the Center’s belief? Your conclusion must be in terms of the P-Value as well as setting up a Rejection Region.

Over the course of his career, his overall made free-throw percentage was 53.3%. During one off- season, Shag had been working with an assistant coach on his free-throw technique. During the next season, a simple random sample showed that Shaq made 26 of 39 free-throw attempts. Test the claim that Shaq has significantly improved his free-throw shooting using a 0.05 significance level. Check the conditions of the Central Limit Theorem for this scenario. Calculate the number of expected successes.arrow_forward
