Question

Given a standardized normal distribution (with a mean of O and a standard deviation of 1), complete parts (a) through (d). Click here to view page 1 of the cumulative standardized normal distribution table. Click here to view page 2 of the cumulative standardized normal distribution table. a. What is the probability that Z is less than 1.05? The probability that Z is less than 1.05 is 8289 (Round to four decimal places as needed.) b. What is the probability that Z is greater than -0.24? The probability that Z is greater than -0.24 is (Round to four decimal places as needed.) c. What is the probability that Z is less than -0.24 or greater than the mean? The probability that Z is less than -0.24 or greater than the mean is (Round to four decimal places as needed.) d. What is the probability that Z is less than -0.24 or greater than 1.05? The probability that Z is less than -0.24 or greater than 1.05 is (Round to four decimal places as needed.)
