Question

1. Use MATLAB’s normcdf() function to solve the following problems. Please include a sketch for each problem along with your handwritten MATLAB script.

a. Calculate the area (probability) from Z = - to Z=1.96

b. Calculate the probability from Z = 0 to Z =2.4

c. Calculate the probability from Z = -1.96 to Z=1.96

2. Use MATLAB’s norminv() function to solve the following problems. Please include a sketch for each problem along with your handwritten MATLAB script.

a. Calculate the value of Z that corresponds to the bottom 2%

b. Calculate the values of Z for a 93% Confidence interval

Explanation / Answer

1) I can solve only one question per thread.

a) Enter normcdf(1.96) in matlab command window and get ans = 0.9750

b) Enter normcdf(2.4) - normcdf(0) and get ans = 0.4918

c) Enter normcdf(1.96) - normcdf(-1.96) and get ans = 0.9500
