According the a 2017 Gallup poll, 80% of Americans report being afflicted by stress. Suppose a random sample of 1000 Americans is selected. To form a 95% confidence interval for the population proportion of Americans afflicted by stress, what conditions of the Central Limit Theorem must be met? Select all that apply. The number of successes from the sample is 800 Americans afflicted by stress, where 800 > 10. The sample size is large enough since the sample size of 1000>25. The population is large enough since there is definitely over 1000 Americans.

50 of the 600 medical students who were chosen at random stated they intended to work in a rural area. Calculate the 90% confidence interval for the actual percentage of medical students who intend to practice in rural areas. The responses shown here are estimates.

Stanford University conducted a study of whether running is healthy for men and women over age 50. During the first eight years of the study, 1.5% of the 451 members of the 50-plus Fitness Association died. We are interested in the proportion of people over 5o who ran and died in the same eight-year period.   Construct a 95% confidence interval for the population proportion of people over 50 who ran and died in the same eight-year period. Explain in a complete sentence what the confidence interval means

Credit card ownership varies across age groups. Suppose that the estimated percentage of people who own at least one credit card is 64% in the 18–24 age group, 84% in the 25–34 age group, 75% in the 35–49 age group, and 77% in the 50+ age group. Suppose these estimates are based on 465 randomly selected people from each age group.

Out of 3064 respondants, 919 of them said they have a dog. Using this data, compute a 95% confidence interval for the true proportion of people who own a dog.

Out of 100 people sampled, 40 had kids. Based on this, construct a 99% confidence interval for the true population proportion of people with kids.

Wildlife biologists inspect 180 deer taken by hunters and find 36 of them carrying Lyme disease ticks. Calculate a 95% confidence interval for the proportion of deer that carry Lyme disease ticks.

Out of 600 people sampled, 42 had kids. Based on this, construct a 99% confidence interval for the true population proportion of people with kids.

A statistics student wants to conduct a study to determine the proportion of workers in Cititon who commute to another town for work. If the student wants a 90% confidence interval with a margin of error of 2%, how many workers should be in her sample?
