= Q4. Energy consumption in 2002, by province, from four major sources: petroleum (21), natural gas (22), hydroelectric power (33), and nuclear electric power (14) is recorded in quadrillions (1015) of BTUs. The resulting mean and covariance matrix are: 0.766 0.856 0.635 0.173 0.096 0.508 X 0.635 0.568 0.128 0.067 0.438 0.173 0.127 0.171 0.039 0.161 0.096 0.067 0.039 0.043 (a) Using the summary statistics, determine the sample mean and variance of the provinces' total energy consumption for these major sources. (b) Determine the sample mean and variance of the excess petroleum consumption over natural gas consumption. [4] (c) Obtain a large sample 95% Bonferroni confidence intervals for the mean con- sumption of each of the four types, the total of the four and the difference, petroleum minus natural gas. [8] (d) Obtain a large sample 95% simultaneous T2 confidence intervals for the mean consumption of each of the four types, the total of the four and the difference, petroleum minus natural gas. Compare with your results from part (c). 19 m
