For a repeated-measures study comparing two treatment conditions, a researcher obtains a sample of n = 9 difference scores with a mean of md = 4 and a variance of s2 = 36. what is the value for the repeated-measures t statistic for these data?

Step-by-step explanation:

Given that for a repeated measures study comparing two treatment conditions, an experiment was conducted.

n=9:  Mean difference =4:

Variance = s^2 =36

Std error =

t statistic = Mean diff/SE

=

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
