Cell Phone Call Lengths The average local cell phone call length was reported to be 2.32 minutes. A random sample of 23 phone calls showed an average of 2.86 minutes in length with a standard deviation of 0.94 minute. At a 0.01, can it be concluded that the average differs from the population average? Assume that the population is approximately normally tu (a) State the hypotheses and identify the claim. Ho = 2.32 not claim H₁ 2.32 claim
