The distribution of the runtimes of all movies is known to be skewed to the left with a mean of 101 minutes and a standard deviation of 11.53 minutes. Use this information to determine the following probabilities. Round solutions to four decimal places, if necessary. Find the probability that a random sample of 92 movies has a mean runtime greater than 99.7 minutes. P(a > 99.7) = Find the probability that a random sample of 92 movies has a mean runtime between 97.2 and 102.1 minutes. P(97.2 < < 102.1) = %3D
