Suppose that the weight of navel oranges is normally distributed with mean u and standard deviation a 8 ounces, = 1.5 ounces. determine t such that p(7.53 s x t) i. 0.8. which value characterizes 5% of navel oranges with lowest weight? b. entry to a certain university is determined by a national test. the sco variable random with a mean of 500 and a standard deviation of 100. if a sample of 40 of i. ores on this test are these scores is taken s determine t such that p(x

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
