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=25.2 | x2= 22.8 |
1=5.9 | 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.)(c)With
= 0.05,
what is your hypothesis testing conclusion?
