Soda cans of a certain kind are labeled as containing 12 ounces. a quality control inspector believes that the mean weight may be more than this, so she performs a hypothesis test of h0: mean = 12 versus h1: mean > 12. she rejects the null hypothesis. which of the following is an appropriate conclusion? a. there is not enough evidence to conclude that the mean weight of the soda in the cans is greater than 12. b. we conclude that the mean weight of soda in the cans is greater than 12.

For which pair of functions is (gof)(a)=|a|-2?

Which of the following represents the length of a diagonal of this trapezoid?

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?
