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 , the t-statistic, and the p-value. From the histogram, can normality be assumed? Pick t= p= Ex: 1.234 Since the p-value is Pick Pick Check than the significance level 0.05, the null hypothesis Pick ✓evidence exists that the mean height differs from 40 feet. Next 3 Feedback?
I know a few steps but I get confused after I add the
