- Find the critical value(s) for the t test for a left-tailed test with n=8 and a=0.05.Using the z table (Table E), find the critical value (or values) for each. A) α = 0.01, left tailed test.A researcher is using a two-tailed hypothesis test with α = 0.05 to evaluate the effect of a treatment. If the boundaries for the critical region are t = ± 2.080, then how many individuals are in the sample?

- What is the critical value for a two-tailed t test when α = 0.02 and d.f. = 18?With a = .01, the two-tailed critical region for a t test using a sample of n = 16 subjects would have boundaries of ?In a sample of 44 men, 35 said that they had less leisure time today than they had 10 years ago. In a sample of 44 women, 28 women said that they had less leisure time today than they had 10 years ago. At a= .01, is there a difference in the proportions?Use p1 for the proportion of men with less leisure time. State the hypotheses and identify the claim H0: H1: one tailed or two tailed Find the critical value(s). Round the answer to at least three decimal places and ensure your degrees of freedom are correct before proceeding. If there is more than one critical value, seperate them with commas. Critical value(s)= Compute the test value. Round sample proportions to three decimal places and z score values to two decimal places. z= Reject or do not reject the null hypothesis Is there enough evidence to support the claim Find the 99% confidence interval for the difference of the two proportions. Round the answers to three decimal places ( ) < p1-p2 < ( )
