The observations within each sample must be independent The two populations from which the samples are selected must be normal The two samples must have equal sample sizes. The two populations from which the samples are selected must have equal variances.

Answer 1

4:

The formula for test statistics is

$t=\frac{MD-\mu_{D}}{s/\sqrt{n}}$

As the sample size increases, test statistics will also incrased. As the MD increases test statistics will also incrased. As the test statistics increases chances of rejecting null hypothesis and getting significant results wll also increased. That is correct option is

n=30 and MD= 4

5:

Second option is correct becuase in this each of subject are treated under two different conditions.

6:

Third option is correct.

7:

First option is correct.

8:

Fourth option is correct.
