Question

can i get help with c and d please

 

= Let z be a standard normal variable. Let x be a normal random variable with mean 12 and standard deviation o 4. For parts (a) and (b), (i) sketch the probability distribution and shade the area corresponding to the probability and (ii) calculate the probability. Make sure your sketches are neat and well-labeled. (a) P(z ≤ 2.37) (b) P(6.28 ≤ x ≤ 17.72) μx = (c) Now, find the upper bound on the lower 12% of z. (d) Find the upper and lower bounds on the middle 75% of x.
