Jump to level 1 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 60 poles to determine if the mean height is 40 feet at a significance level of 0.05. Create a histogram, and calculate a, the t-statistic, and the p-value. From the histogram, can normality be assumed? Pick v c = Ex: 1.234 t = p : Since the p-value is Pick than the significance level 0.05, the null hypothesis Pick Pick evidence exists that the mean height differs from 40 feet
