You are given two identical balls made of a tough alloy. The hardness test fails if a balldropped from a floor of a 120-storey building is dented upon impact. A ball can bereused in fresh drops only if it has not been dented in a previous drop. Using only thesetwo identical balls, what is the smallest number of ball drops that will determine the high-est floor from which the ball can be dropped without being damaged?

To find the highest floor from which a ball can be dropped without being damaged, we can use a…

Jerry is considering opening a new ice cream store at a certain location on State Street in Madison. Jerry conducts some analysis and determines that a given location is acceptable only if the number of pedestrians passing the potential location averages more than 100 per hour. To check if this location is acceptable, Jerry records the number of pedestrians observed for each of 40 hours. Jerry finds that the average number of pedestrians that pass the potential location during each of the 40 hours he was observing, is 105.7 per hour. Jerry assumes that he knows the population standard deviation to be 16. Can Jerry conclude at the 1% significance level that the potential location for the ice cream store is acceptable? a. What is the correct set of hypotheses? Answer: Ho: u = 100 and H1: u> 100 v b. Determine the p-value Answer: 0.0122 c. Interpret the results Answer: There is not enough evidence d.
