Suppose that the mean time to download a home page of a website is 1.2 seconds. Given that the download time is normally distributed= with a standard deviation of 0.2 second. 1What is the probability that a download time is: (a) less than 1.5 seconds? (-1- dp.) Prob = 0.999? (b) between 1.6 and 1.9 seconds? (11- dp.) Prob = 0.9332 (c) above 1.8 seconds? (4 d.p.) Prob = 0.0013 (d) 915% of the download times are slower (higher) than how many seconds? (3 d.p.) (e) 90% of the download times are between what two values, symmetrically distributed around the mean? {3 rip.) 40% from the top 60%. A bank's loan officer rates applicants for credit. The rating are normally distributed with a mean of 200 and a standard deviation of 50. Find P40, the score which separates the lower O 211.3 207.5 O 187.5 O 212.5
