- You obtain a t comp of .975 in a two sample independent t test with alpha at .05. Is it significant?With α = .05, what is the critical t value for a one-tailed test with n = 15?If the df value for a two tailed test with alpha =0.05 were to increase from df=5 to df=22,what would happen to the critical values for t?
- If the test of H0: = 19 against Ha: ≠ 19 based on an SRS of 15 observations from a Normal populationproduces the statistic of t = –1.75. The P-value isFor a 98% confidence interval of the population mean based on a sample of n = 20 with s = 0.05, the critical value of t is:In a test of H0: µ=150 against HA: µ<150, a sample of size 250 produces Z = -0.65 for the value of the test statistic. Thus the p-value is approximately equal to
