The distribution of the runtimes of all movies is known to be skewed to the left with a mean of 114 minutes and a standard deviation of 5.05 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 89 movies has a mean runtime greater than 114.1 minutes. P(> 114.1) Find the probability that a random sample of 89 movies has a mean runtime between 114.3 and 115.7 minutes. P(114.3 << 115.7) -
