10 1 point Problem 2d) A different claim is made that the average traffic flow past the school is less 9000 cars/day. Based on this claim, what is the calculated p-value, using the normal distribution 0.977 0.186 0814 O 00228 11 1 point Problem 2e) Based on the results of the hypothesis test from 2d, and given a significance of 0.05, we should O fail to reject the null. The data do not support the claim that the average traffic flow is less than 9000 cars/day. reject the null in favor of the alternative. The average traffic flow is less than 9000 cars/day. 12 1 point Problem 3.
