exercise 7.19 - inverse cumulative distribution function using normal distribution Let z denote a variable having a normal distribution with mean O and std. deviation * 1. Determine value of such that the probabilities are satisfied. Hint: draw a picture of the area under the curve being requested, and then figure out how to use R language functions to calculate it. A Question 8 (1 point) Retake question a) P(z < z*) = .025 A Question 9 (1 point) Retake question d) P(z > z*) = .02 A Question 10 (1 point) Retake question f) P(z > z* or z < -z*) = .20
