Question

P= ?

Test whether un <H2 at the a= 0.01 level of significance for the sample data shown in the accompanying table. Assume that the populations are normally distributed. 3Click the icon to view the data table. Determine the null and alternative hypothesis for this test. 1 Sample Data O A. Hoita <H2 HqEH41 = H2 O B. Ho:H1 = 42 H4:4 * H2 | O C. How * H2 HH1 H2 D. Ho:11=H2 H:H1 <H2 SIX on Population 1 33 103.4 12.2 Population 2 25 114.2 13.2 Detemine the P-value for this hypothesis test. Print P= Print (Round to three decimal places as needed.) Done Done

Answer 1

Ho:41-42 Ha: 41-42 = < pop 2 x pop 1 = 103.400 X - 12.2002 33 m2 114.200 13.200 ny Point estimate =x1-x2= -10.800 degree of freedom v ='min(n1,n2)-1= 24 for 0.01 level left tail test 824 df, critical t= -2.492 Decision rule: reject Ho if test statistic <2.492 std error = (Sy/n+s*z/nz)= 3.388 test statt =(x1-x2-40)/Se = p value: - -3.188 0.002

from above p value =0.002 (please try 0.001 if this comes wrong and reply)
