Statistics- The rejection region for the standardized test statistic

QUESTION

Random samples of female and male drivers are asked to estimate the number of miles that each drives in a year. The data is below:Females (Population 1): 9900, 8400, 8400, 8400, 9800, 8500, 8700, 8400, 8600Males (Population 2): 10800, 9400, 10600, 11000, 9300, 9700, 10200Is there evidence, at an α=0.02 level of significance, to conclude that there is a difference in the number of miles driven between females and males? Carry out an appropriate hypothesis test, filling in the information requested.A. The value of the standardized test statistic:Note: For the next part, your answer should use interval notation. An answer of the form (−∞,a) is expressed (-infty, a), an answer of the form (b,∞) is expressed (b, infty), and an answer of the form (−∞,a)∪(b,∞) is expressed (-infty, a)U(b, infty).B. The rejection region for the standardized test statistic:
