Example 2: A group of statisticians in 2010 concluded that the mean amount of time people Mu in Virginia spend on their cell phones per day is 180 minutes. A group of statisticians claims M that the mean time has since increased. They surveyed 100 Virginia residents and found that the mean amount of time people use their cell phones is 189 minutes per day. Assume the o is 50. Perform a hypothesis test at the 0.05 significance level to test the claim that the actual mean time that Virginians spend on their cell phones per day is greater than 180 minutes.
