Consider the hypothesis statement shown below using =0.01 and the data to the right from two independent samples.

H0:12=0 x1=192 x2= 220

H1:120 1=51 2=61

n1=42 n2=35

a) Calculate the appropriate test statistic and interpret the result.

b) Calculate thep-value and interpret the result.

a) The test statistic is?

Determine the appropriate criticalvalue(s). Select the correct choice below

A. The critical values are ?

B. The critical value is ?

Since the test statistic (does not fall/fall) in the rejectionregion, (do not reject/reject) H0. There is (insufficient/sufficient) evidence to conclude that the mean of population 1 is different from the mean of population 2.

Thep-value is

Since thep-value is (less,greater,equal), ,(?). H0. There is (insufficient/ sufficient) evidence to conclude that the mean of population 1 is different from the mean of population 2
