Use Sheet 8 of the Excel file to answer the following questions. A power company is installing utility poles that are supposed to have a height of 40 feet. The foreman checks a random sample of ED poles to determine ifthe mean height is 40 feet at a significance level of 0.05. Create a histogram, and calculate E, the fstatistic, and the p-value. From the histogram, can normality be assumed? PiCk V E = EX: 1 .234 t = p = Since the pualue is Pick V than the signicanoe level 0.05, the null hypothesis Pick V - Pick 9 evidence exists that the mean height differs from 40 feet
