Anew centrifugal pump is being considered for an application involving the pumping of ammonia. the specification is that the flow rate be more than 5 gallons per minute (gpm). in an initial study, eight runs were made. the average flow rate was 6.5 gpm and the standard deviation was 1.9 gpm. if the mean flow rate is found to meet the specification, the pump will be put into service. 1. state the appropriate null and alternate hypotheses

2. find the p-value

3. should the pump be put into service? explain.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
