Iverage an omobille insur iceT $605. Suppose that in a simple random sample of 80 residents of New York, for most recent year their average expenditure was $638.62 with the standard deviation of $106.05. Based on these data, examine whether th average annual insurance for motorists in New York might be different from that in national level. Using the 0.05 level of significance, what conclusion do you reach? Also, construct and interpret 95% confidence interva for the population mean. Is the hypothesized mean within the interval? Is this consistent with the findings o the hypothesis test conducted?
