# Using the sample results in exercise 10.54, construct and interpret the 90% confidence interval for the population mean. is the hypothesized population mean (38 minutes) within the interval? given the presence or absence of the 38 minutes value within the interval, is this consistent with the findings of the hypothesis test conducted in exercise 10.54?

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 aÃ¢â€ Âµect the mean and standard deviation of the wait time until success?
