$Help with the following attached: \fI In a random sample of eight$ beams constructed of engineered wood the load x at which each beam

\fI In a random sample of eight beams constructed of engineered wood the load x at which each beam fails under successively heavier loading is recorded. The results are a? = 4085 and s = 221. Assuming that the population of maximum loads for all such beams is normally distributed, a 99% confidence interval for the mean maximum load for all such beams is: (a) 4085 i (2.576)(% 221 (b) 4085 i (2.681)() 221 (c) 4085 i (3.499)() 221 (d) 4085 i (3.053(3) (e) 4085 i (2.896)(%)
