Question:

Two samples of sizes 15 and 20 are randomly and independently selected from two normally distributed populations, where the unknown population variances are assumed to be equal.

The number of degrees of freedom associated with the two-sample t-test is equal to 35. True of False?

Two sample t-test

Here we need to find the degrees of freedom for two sample t-test

Answer and Explanation:

False

Degrees of freedom associated with two sample t-test is {eq}n_{1}+n_{2}-2 {/eq}

= 10+15-2=33
