Assume that the paired data came from a population that is normally distributed. Construct a 95% confidence interval for the mean of all differences x – y
x_i 11 13 17 8 6 9 15 9
y_i 6.0 10.0 14.0 5.0 11.0 7.0 14.0 13.0
Find the 95% confidence interval
______ < ų_d < ________ (round to nearest decimal place as needed)
