11.29 Glucose testing, continued. Shelia's measured glucose level one hour after a sugary drink varies according to the Normal distribution with 10 mg/dl. What is the level L such that there is probability only 0.05 that the = 125 mg/dl and backward 0 = mean glucose level of 4 test results falls above L? (Hint: This requires a Normal calculation. See page 83 in Chapter 3 if you need to review.)

11.29 Glucose testing, continued. Shelia's measured glucose level one hour after a
sugary drink varies according to the Normal distribution with u = 125 mg/dl and
o = 10 mg/dl. What is the level L such that there is probability only 0.05 that the
mean glucose level of 4 test results falls above L? (Hint: This requires a backward
Normal calculation. See page 83 in Chapter 3 if you need to review.)
