Based on the values in the table, the repeated measures t statistic would be b. -0.577.
What is the repeated-measures t-statistic?
The test statistic can be found as:
= (Mean difference - μd) / (Standard deviation / sample square root)
These figures can be found in a spreadsheet to be:
μd = 0
Mean difference = -1
Standard deviation = 3.4641
The test statistic is therefore:
= (-1 - 0) / (3.4641 / √4)
= - 0.577350269
= - 0.577
