Answer:

value = 8

Step-by-step explanation:

when a paired-samples t test is used by this researcher we will write out the hypothesis as follows

H0: μd ≤ 8 ( null )

Ha: μd > 8 ( alternate )

Given the above Hypothesis

If a paired-sample T test is used by the researcher the value that would be at the center of the comparison will be 8
