Using a Q-Q plot, test the data xi1 : 93, 94, 95, 96, 97, 98, 99, 100, 101, 102. xi2 : 52.33, 53.46, 54.18, 54.69, 55.04, 52.29, 56.28, 59.48, 61.81, 63.71. for bivariate normality. Attach the Q-Q plot that you obtain. Use a graphing calculator to sketch the 95 percent confidence region for d = (x – a)"S-1(x – a) above and plot the points (x;1, Xi2), i system. Based on the figure you obtain, does it seem reasonable that (X1, X2) follows a bivariate for the data in Problen = 1, ..., 10 in the same coordinate normal distribution? Attach the figure and justify your answer.

for bivariate normality. Attach the Q-Q plot that you obtain.
Use a graphing calculator to sketch the 95 percent confidence region for
d² = (x – ¤)"S-'(x – ¤)
for the data in Problen
above and plot the points (xi1, xi2), i = 1, ..., 10 in the same coordinate
system. Based on the figure you obtain, does it seem reasonable that (X1, X2) follows a bivariate
normal distribution? Attach the figure and justify your answer.
