Part 1 A population of values has a normal distribution with μ=135.9 and σ=18.1. You intend to draw a random sample of size n=96.Find P61, which is the score separating the bottom 61% scores from the top 39% scores.P61 (for single values) = Find P61, which is the mean separating the bottom 61% means from the top 39% means.P61 (for sample means) = Part 2 The town of KnowWearSpatial, U.S.A. operates a rubbish waste disposal facility that is overloaded if its 5030 households discard waste with weights having a mean that exceeds 26.49 lb/wk. For many different weeks, it is found that the samples of 5030 households have weights that are normally distributed with a mean of 26.23 lb and a standard deviation of 12.49 lb.What is the proportion of weeks in which the waste disposal facility is overloaded?P(M > 26.49) =
Part 1
