You sampled 200 Twitter stock prices. Suppose that you found the sample mean stock price to be c = $30:00 with a standard deviation of sc = $12:50 . (a) Suppose that a stock exchange has claimed that the true mean Twitter stock price is only $28. To test this claim, perform a hypothesis test at the α = 0:02 significance level to determine whether the sample provides evidence that the true mean Twitter stock price differs from the stock...

A community survey sampled 1923 people in Colorado and asked them how long it took them to commute to work each day. The sample mean one-way commute time was 25.3 minutes with a standard deviation of 13 minutes. A transportation engineer claims that the mean commute time differs from 25 minutes. Do the data provide convincing evidence that the engineer's claim is true? Use the α=0.01 level of significance and the P-value method with the Critical Values for the Student's...
