Consider the following hypothesis test.

H0: 1 - 2 = 0

Ha: 1 - 2 0

The following results are from independent samples taken from two populations.

Sample 1 Sample

2 n 1 = 35 n 2 = 40

x 1 = 13.6 x 2 = 10.1

s 1 = 5.5 s 2 = 8.3

Consider the following hypothesis test. The following results are from independent samples taken from two populations. Sample 1 135 X 1 = 13.6 S1 -5.5 a. What is the value of the test statistic (to 2 decimals)? Sample 2 n2=40 X 210.1 S2 -8.3 b. What is the degrees of freedom for the t distribution? (Round down your answer to the whole number) c. What is the p-value? Use z-table. The area in the upper tail is between .01 and .025 d. At -.05, what is your conclusion? p-value is less than or equal to 0.05, reject Ho ; two-tailed p-value is between between.02 and .05 v
