Question: Consider the following hypothesis test. H 0 : 1 2 0 H a : 1 2 > 0 The following results are for two independent

Consider the following hypothesis test.

H0:120

Ha:12> 0

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

Sample 1 Sample 2

n1= 40 n2= 50

x1=25.9 x2= 22.8

1=5.4 2= 6

(a) What is the value of the test statistic? (Round your answer to two decimal places.)

(b) What is thep-value? (Round your answer to four decimal places.)
