Construct a confidence interval for ud, 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.

a 5.0 5.1 4.6 3.5 6.0

b 4.7 3.9 4.2 4.2 3.7

a 0.22< ud < 7.48

b -0.37 <ud <1.77

c -0.07 < ud < 1.47

d -.31 <ud <1.71
