Question

2. Create the printout for testing whether the mean high stock price of all NASDAQ stocks differs from $30.00 and attach it here. Answer the following questions regarding this printout: One-Sample T Test Null Hypothesis: u = 30 Alternative Hyp: u * 30 Variable HIGH Mean 42.976 P 0.4723 Lower 956 C.I. 6.2991 Upper 95% C.I. 79.653 SE TDF 17.771 0.73 24 Missing Cases 0 Cases Included 25 a. State the assumption in the words of the problem) necessary for this printout to be valid. b. Use the p-value given in this problem to state the conclusion that you would make in the words of the problem. Make sure you include the value of a that you select as part of this conclusion. c. Suppose it was really desired to conduct a one-tailed test instead of the two-tailed test. Use your knowledge of p-values to write in the space below the value of the one-tailed p-value that should be used in the interpretation of the results. One-tailed p-value =

Answer 1

6 The data comes from random sample n is sufficiently large The data comes from Nonnal population Here, P-value > level of significance 0.05 we fail to Reject the null hypothesis. There is so not sufficient evidance to Support the claim mean high stock price of all NASDAQ Stocks are different from 30. One tailed p-value = 0.4723 2016 = 0.23621
