A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 68%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H: 0

In a recent Super Bowl, a TV network predicted that 17 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 141 people who saw the commercials and found that 31 of them said they would watch one of the television shows.Suppose you have the following null and alternative hypotheses for a test you are running:H0:p=0.17Ha:p>0.17Calculate the test statistic, rounded to 3 decimal places

Suppose that a 2013 survey revealed that 69.1% of recent college graduates had student loan debt. Amy suspects that this proportion has increased, so she formulated the null hypothesis Ho: p = 0.691 and the alternative hypothesis H₁: p > 0.691, where p is the proportion of 2015 college graduates who have student loan debt. She obtained a simple random sample of 200 college graduates from the class of 2015 and found that 147 of them have student loan debt. Using this information, she calculated the following summary statistics. Sample Sample Sample size count proportion n 200 X 147 The decision is to null equal to (p-value = 0.092).

Female college student participation in athletics has increased dramatically over the past few decades. Sports medicine providers are aware of some unique health concerns of athletic women, including disordered eating. A study compared disordered-eating symptoms and their causes for collegiate female athletes (in lean and non lean sports) and nonathletes. The sample mean of the body dissatisfaction assessment score was 13.4 (s=7.9) for 15 lean sports athletes (those sports that place value on leanness, including distance running, swimming, and gymnastics) and 7.4 (s=5.8) for the 67 non-lean athletes. Assume equal population standard deviations. Find the standard error for comparing the means. Construct a 95% confidence interval for the difference between the mean body dissatisfaction for lean sport athletes and non lean sport athletes. Interpret.

You are conducting a study to see if the proportion of voters who prefer the Democratic candidate is significantly larger than 53% at a level of significance of a = 0.10. According to your sample, 42 out of 69 potential voters prefer the Democratic candidate. a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? ✓ Select an answer H₁: ? Select an answer (please enter a decimal) (Please enter a decimal) c. The test statistic ? d. The p-value = e. The p-value is ? ✓ a f. Based on this, we should Select an answer the null hypothesis. (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.)

Which of the following is correct about tests of hypotheses? Question 11 options: If we take a large enough random sample, any effect (however small) will be deemed statistically significant. The measure of statistical significance (a P- value) depends heavily on the sample size. Practical significance is not the same thing as statistical significance. If the consequences of rejecting the null hypothesis are very serious, we should conduct the test using a very small level of significance. All the statements above are true.
A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72% . Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0 : H1 :
