Question: The null hypothesis is Ho:u1 = u2 and the alternative hypothesis is as specified. The data available below are from a simple random paired sample

The null hypothesis is Ho:u1 = u2 and the alternative hypothesis is as specified. The data available below are from a simple random paired sample from the two populations under consideration. Use the paired? t-test to perform the required hypothesis test at the 5?% significance level. Ha :u1 < u2.

	Observations for-
Pair	Population 1	Population 2
1	13	15
2	22	26
3	11	12
4	25	21
5	22	28
6	25	25
7	8	10
8	22	30
9	1	3

Refer to a T-table.

1. Find the test statistic. Use population 1 - population 2 as the difference. t = ? (Round to two decimal places as needed.)

2. Determine the critical value(s). (Round to two decimal places as needed.)

Pick- a. The critical value is ? . or b. The critical values are ? and ? . (Use ascending order.)

3. What is the correct conclusion for the hypothesis test?
