Mrs. gainey planned a dinner for 15 people this . she bought 22.5 lbs of turkey, plus potatoes, cranberry salad, rolls and all of the traditional holiday food. unfortunately, her daughter forgot to tell her that she was bringing three of her college friends. if mrs. gainey wanted to feed each person the same amount of turkey that she had originally planned, how much additional turkey must she purchase to accommodate these additional guests? express your answer as a decimal to the nearest tenth. what percent is each person’s intended serving of turkey reduced?

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?

Use a standard normal table to determine the probability. give your answer as a decimal to four decimal places. −1.5< < 1.5)
