CI on Mean, Variance Known As a study being conducted by the state's Land Transportation Bureau, a random sample of 150 SUV owners in Alabama shows than an SUV is driven on average 25,000 kilometers per year with a standard deviation o of 5,200 kilometers. Assume the distribution of samples to be approximately normal. kilometers Construct a 99% confidence interval for the average number of kilometers an SUV is driven annually. What can we assert with 99% confidence about the possible size of our error if we estimate the average number driven by SUV owners in Alabama to be 25,000 kilometers per year? O a. 99% CI: 23909
