V t Stat P(T> =t) one-tail t Critical one-tail P(T>=t) two-tail 0.086 t Critical two-tail 2.003A large car insurance company is conducting a study to see if male and female drivers have the same number of accidents, on average, or if male drivers (who tend to be thought of as more aggressive drivers) have more. Data set on the number of accidents in the past 5 years is collected for randomly selected drivers who are insured by this company. An analysis of results at a = 0.05 produced the following output (incomplete).Question 10 Calculate the test statistic (assume equal variances).
