Question

HoneWOrK.nomewOIK ChapterSection T (He Score: 0 of 1 pt 41 of 7 (0 cor Determine the appropriate critical value(s) for each of the following tests concerning the population mean: a. upper-tailed test: .-0.05; n 36 #3.0 b. lower-tailed test: = 0.10: n = 30, s=6.0 c, two-tailed test: : 0.02; n= 41; s= 6.8 d, two-tailed test: =0.20; n#25; = 5.6 a. Determine the appropriate critical value for an upper-tailed test: :0.05; n:36; = 3.0. The critical value(s) is(are Round to two decimal places as needed. Use a comma to separate answers as needed.)

Explanation / Answer

9.1.1 T

critical value for

alpha=0.05 and upper tail

1.96

Solution9.1.5-T

z=X-MU/SD/SQRT(N)

Z=105-113/25/sqrt(47)

Z stat=-2.19

z crit for 99%= 2.576

Since z stat< Z crit

Fail to reject Ho

Decision rule is

reject Ho if the calculated value of test statistic is greater than the critical value otherwise do not reject null hypothesis
