Question

The null hypothesis for a two-tailed repeated-measures test states: Group of answer choices The entire population will have a mean difference of μD = 0. The overall sample will have a mean difference of MD = 0. The entire population will have a mean difference of µD ≠ 0 The overall sample will have a mean difference of MD ≠ 0.

Answer 1

Answer:

The entire population will have a mean difference of μD = 0.

Step-by-step explanation:

This case is a null hypothesis for a test of repeated measures of two tails. The general null hypothesis is a hypothesis of no difference. We must find the differences of each pair and then find the mean of these differences.

Under a null hypothesis it is established that the population mean of the differences is 0.

Therefore, the correct option is the entire population will have a mean difference of μD = 0 (first option).

Second option is incorrect: It considers the sample instead of the population.

Third option is incorrect: It says that the mean difference is different from zero.

Forth option is incorrect: It says that the mean difference is different from zero.

Hope this helps!
