Question:
A researcher is evaluating if the mean difference between two populations differs from zero. To do this, the researcher takes a sample of 40 paired observations (n = 40) and finds the mean difference is 0.62 ( ̄d = 0.62) and the standard deviation is 1.32 (SD= 1.32). Assume that the population data is normally distributed. Construct a confidence interval at the 95% confidence level.
