The P-value of a test of a null hypothesis is (A) The probability, assuming the null hypothesis is true, that the test statistic will take a value at least as large as that actually observed ... Use a smaller confidence level (C) Use the same confidence level, but compute the interval n times. Approximately 5% of these intervals will be larger ...

56. B The hypothesis was not rejected at level alpha=.05.So p value was higher than 0.05 and so higher than 0.025 as well. So the test will again fail to reject the null hypothesis at level =0.025. 57. A The hypothesis was rejected at level=0.01.So, p value was less than 0.01 and so less than 0.10 as well.

confidence interval is 95%, then the corresponding significance level, (, is 1 –0.95 = 0.05. Thus, we can see that since p-value < 0.05, which would result in a rejection of the null hypothesis; we will reject the assumed µ value, 30.

(P-Values for t tests are given by SPSS as Sig (2 tailed) and must be divided by 2 for one-side tests). One side P Value = .0235. A confidence interval or statistical test is called robust if the confidence level or P-value does not change very much when the assumptions of the procedure are violated.
