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.
