Question
Consider the hypothesis statement to the right using alpha = 0.01 and the data to the right from two independent samplers. a) Calculate the appropriate test statistic and interpret the result. b) Calculate the p- value and interpret the result. Click to view page 1 of the standard normal table. Click here to view page 2 of the standard normal table. a)The test statistic is (Round to two decimal places as needed.) H_0: mu_1 - mu_2 lessthanorequalto 0 H_1: mu_1 - mu_2 > 0 x_1 bar = 82 x_2 bar = 75 Sigma_1 = 30 sigma_2 = 18 n_1 = 55 n_2 = 60Explanation / Answer
using minitab
Two-Sample T-Test and CI
Sample N Mean StDev SE Mean
1 55 82.0 30.0 4.0
2 60 75.0 18.0 2.3
Difference = (1) - (2)
Estimate for difference: 7.00
99% lower bound for difference: -4.06
T-Test of difference = 0 (vs >): T-Value = 1.50 P-Value = 0.069 DF = 86
T-Value = 1.50
P-Value = 0.069
