Refer to Example 12.12 in which x 5 test track speedand y 5 rolling test speeda. Minitab gave sb01b1s45d 5 .120 and sb01b1s47d 5 .186.Why is the former estimated standard deviationsmaller than the latter one?b. Use the Minitab output from the example to calculatea 95% CI for expected rolling speed when testspeed 5 45.c. Use the Minitab output to calculate a 95% PI for asingle value of rolling speed when test speed 5 47.
