Construct a confidence interval for μd, the mean of the differences d for the population of paired data. Assume that the population of paired differences is normally distributed. Using the sample paired data below, construct a 90% confidence interval for the population mean of all differences x - y.

X= 5.0, 5.1,4.6,3.5,6.0

Y= 4.7, 3.9,4.2,4.2,3.7
