Recent research has found that 10% of Americans aged 30-49 played tennis in the past 12 months. A local city wishes to test whether this is true in their city as well. If more than 10% of their residents aged 30-49 play tennis, improvements will be made on their tennis courts. A random survey of 200 residents aged 30-49 found that 48 played tennis. Do we have evidence that more than 10% of the residents play tennis? Use α=.05.

Based on information from a previous study, r1 = 38 people out of a random sample of n1 = 105 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 105 adult Americans who did attend college, r2 = 49 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend college? Use α = 0.01. 1. What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.) 2. Find (or estimate) the P-value. (Round your answer to four decimal places.)

Based on information from a previous study, r1 = 38 people out of a random sample of n1 = 106 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 106 adult Americans who did attend college, r2 = 52 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend college? Use α = 0.01.

Based on information from a previous study, r1 = 30 people out of a random sample of n1 = 107 adult Americans who did not attend college believe in extraterrestrials. However, out of a random sample of n2 = 107 adult Americans who did attend college, r2 = 46 claim that they believe in extraterrestrials. Does this indicate that the proportion of people who attended college and who believe in extraterrestrials is higher than the proportion who did not attend college? Use ? = 0.01.

A market researcher claims that the purchases for a particular gift item are men, 50 percent; women, 40 percent; and children under 18, 10 percent. The researcher takes a sample in a very large department store and finds in a given week that 43 items were purchased by men, 33 by women, and 4 by children under 18. Does the evidence support the claim of the market researcher? Use alpha = 0.05
A survey in 2019 asked a random sample of U.S. adults if they believed the government was tracking all or most of their activities online or on their cell phones. Of the 671 adults aged 18–29, 396 said “yes.” Of the 977 adults aged 65 or older, 293 said “yes.” Do we have evidence to claim that the proportion is higher among the young adults as compared to the older adults? (test hypothesis at level alpha =0.05).
A poll of 700 frequent and occasional fliers found that 450 respondents favored a ban on cellphones in flight, even if technology permits it. At α = .05, can we conclude that morethan half the sampled population supports a ban?
A well-known study of 22,000 male physicians was conducted to determine if taking aspirin daily reduces the chances of a heart attack. Half of the physicians were given a regular dose of aspirin while the other half was given placebos. Six years later, among those who took aspirin, 104 suffered heart attacks while among those who took placebos, 189 suffered heart attacks. Does it appear that the aspirin can reduce the number of heart attacks among the sample group that took aspirin? Use α = 0.05.
A double-blind randomized experiment compared the effects of the drug Lorcaserin and a placebo on weight loss in overweight adults. All subjects were also required to undergo diet and exercise counseling. The study involved 1000 participants where half of them would take Lorcaserin and half the placebo. The researchers found that after a year the treatment group had an average weight loss of 5.8 kg while the placebo group had an average weight loss of 3.9 carmona, kg. Based on this information researchers need to decide if Locarserin can be a possible treatment for weight loss. a. What would be a Type I error in this context? Your answer should consist of both the researchers’ decision and what the reality is. b. What would be a Type II error in this context? Your answer should consist of both the researchers’ decision and what the reality is.
