What is the estimated standard deviation of the difference scores?(four decimals)

Extracted text: Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis Ho: Hp - 0 (th null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measuremen A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. A B Observation 1 1 3 4 7 4 8 9 3. 3. 4.
