Researchers suspect that 20% of all high school students smoke at least one pack of cigarettes a day. At Wilson High School, a randomly selected sample of 300 students found that 57 students smoke at least one pack of cigarettes a day. At α = 0.05, test the claim that fewer than 20% of all high school students smoke at least one pack of cigarettes a day.

Two researchers conduct separate studies to test Ho: p=0.50 against Ha: p0.50, each with n = 400. Researcher A gets 225 observations in the category of interest, and p=225/400 =0.5625. Researcher B gets 227 in the category of interest, and p=227/400 = 0.5675. Complete parts (a) through (e) below. A ... OB. Hypothesis tests that produce similar P-values always have the same conclusion. OC. Hypothesis tests that result in the same conclusion do not necessarily have the same P-value. D. A difference in conclusions between two hypothesis tests does not necessarily mean that the test with the result that is deemed "statistically significant" is actually much more significant than the test with the result that is deemed "not statistically significant." d. From part a, part b, and part c, explain why important information is lost by reporting the result of a test as "P-value ≤0.05" versus "P-value > 0.05," or as "reject Ho" versus "Do not reject Ho," instead of reporting the actual P-value.…
According to the USDA, 46.2% of males between 20 and 39 years old consume the minimum daily requirement of calcium. After an aggressive “Got Milk?” campaign, the USDA conducts a survey of 48 randomly selected males between the ages of 20 and 39 and finds that 32 of them consume the recommended daily allowance of calcium. At the alpha=0.10 level, is there evidence to conclude that the percentage of males between the ages of 20 and 39 who consume the minimum recommended daily allowance of calcium has increased?
A study of parental empathy for sensitivity cues and baby temperament (higher scores mean more empathy) was performed. Let x1 be a random variable that represents the score of a mother on an empathy test (as regards her baby). Let x2 be the empathy score of a father. A random sample of 33 mothers gave a sample mean of x1 = 69.72. Another random sample of 36 fathers gave x2 = 59.72. Assume that σ1 = 11.55 and σ2 = 11.45. Let μ1 be the population mean of x1 and let μ2 be the population mean of x2. Find a 99% confidence interval for μ1 – μ2. (Round your answers to two decimal places.) upper limit? lower limit?
In an early home game, an NBA team made 66 of their 100 free throw attempts. In one of theirlast home games, the team made 68 of 90 attempts. At α = .10, did the team significantlyimprove its free throw percentage (left-tailed test)?
If a researcher obtains a sample mean of M= 54, from a population with u = 46. With a given alpha, which combination of factors is most likely to result in rejecting the null hypothesis?
suppose that 43% of people who enter a store will make a purchase. Random samples of people who walk into a particular store is studied, and the proportion of those who made a purchase is found for each sample. Assume that all the samples were the same size. If 29.46% of all sample proportions are less than 0.3274. What was the z-score for 0.3274? What is σp′?
A survey claims that 9 out of 10 doctors (i.e., 90%) recommend brand Z for their patients who have children. To test this claim against the alternative that the actual proportion of doctors who recommend brand Z is less than 90%, a random sample of doctors was taken. Suppose the test statistic is z = -1.95. Can we conclude that H0 should be rejected at the and level? Group of answer choices a) yes; b) yes; c) no a) no; b) no; c) yes a) yes; b) yes; c) yes a) no; b) no; c) no
A weight-lifting coach claims that weight-lifters can increase their strength by taking vitamin E. To test the theory, the coach randomly selects 9 athletes and gives them a strength test using a bench press. Thirty days later, after regular training supplemented by vitamin E, they are tested again. The results are listed below. Use the Wilcoxon signed-rank test to test the claim that the vitamin E supplement is effective in increasing athletes' strength. Use α = 0.05.
A report by the Gallup Poll found that a woman visits her doctor, on average, at most 5.8 times each year. A random sample of 20 women results in these yearly visit totals.

In a 4-week study about the effectiveness of using magnetic insoles to treat plantar heel pain, 51 subjects wore magnetic insoles and 47 subjects wore nonmagnetic insoles. The results are shown at the right. At α=0.06, can you support the claim that there is a difference in the proportion of subjects who feel better between the twogroups? Assume the random samples are independent. Complete parts (a) through (e).
700 doctors went through extra training compared to 1200 doctors who did not. Of the doctors who went through extra training, 125 of them majored in psychology. Of the 1200 doctors who did not do extra training, 174 of them majored in psychology. Perform a hypothesis test to see if there is a statistically significant evidence that the proportion of doctors who went through extra training is significantly greater than the proportion of doctors who did not. Perform the test at the alpha = .5 level. What is the p value and conclusion of this test?
In a survey of 240 males ages 20 to 24, 38% were neither in school nor working. In a survey of 210 females ages 20 to 24, 42% were neither in school nor working. These samples are random and independent. At α=0.06, can you support the claim that the proportion of males ages 20 to 24 who were neither in school nor working is less than the proportion of females ages 20 to 24 who were neither in school nor working?
