For a normal distribution, verify that the probability (rounded to two decimal places) within a. 1.97 standard deviations of the mean equals 0.95. b. 0.53 standard deviations of the mean equals 0.40. c. Find the probability that falls within 0.33 standard deviations of the mean. d. Sketch these three cases on a single graph. Click here to view page 1 of the standard normal table. Click here to view page 2 of the standard normal table. a. Choose the correct response from the following. O A. Looking up 1.97 in a standard normal distribution table, the cumulative probability is 0.0244. The cumulative probability is 0.9756 for 1.97. 0.9756-0.0244 = 0.9512, which rounds to 0.95. O B. Looking up 1.97 in a standard normal distribution table, the cumulative probability is 0.9756. Likewise, the cumulative probability is 0.0244 for - 1.97. 0.9756 -0.0244 = 0.9512, which rounds to 0.95. O C. Looking up 1.97 in a standard normal distribution table, the cumulative probability is 0.9512, which rounds to 0.95
