Question 1 The foundation for a building is designed to rest on 100 piles based on the individual pile capacity of 80 tons. Nine test piles were driven at random locations into the supporting soil stratum and loaded until failure of each pile occurred. The results are as follows (in tons): 82 tons 92 tons 75 tons 78 tons 95 tons 85 tons 90 tons 80 tons 88 tons a. At the 5% significant level, should the piles be accepted based on the results of the nine test piles? That is, to perform a one-sided hypothesis test, with the null hypothesis that the mean capacity is 80 tons. Find the P- value. b. Explain how the question in part (a) could be answered by using a one-sided confidence interval (CI) on the true. mean of the pile capacity?
