Question

Problem 2. A 5-day traffic study measuring the traffic flow by a school collected the following data for daily vehicle count. Daily average = 7632 cars; Daily standard deviation = 1530 cars Problem 2a) If a 99% 1-sided upper confidence bound were to be written for the daily average, what t value would be used in the calculation? 3.365 4.032 3.747 4.604 Problem 2b) Based on the data in the problem statement, we can definitively say that cars/day for traffic flow by the school. True False. 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. 0.814 0.977 0.186 0.0228 Problem 2e) Based on the results of the hypothesis test from 2d, and given a significance of 0.05, we should a) fail to reject the null. The data do not support the claim that the average traffic flow is less than 9000 cars/day. b) reject the null in favor of the alternative. The average traffic flow is less than 9000 cars/day.

          Problem 2.
A 5-day traffic study measuring the traffic flow by a school collected the following data for daily
vehicle count.
Daily average = 7632 cars;
Daily standard deviation = 1530 cars
Problem 2a)
If a 99% 1-sided upper confidence bound were to be written for the daily average, what t value
would be used in the calculation?
3.365
4.032
3.747
4.604
Problem 2b)
Based on the data in the problem statement, we can definitively say that cars/day for traffic flow
by the school.
True
False.
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.
0.814
0.977
0.186
0.0228
Problem 2e)
Based on the results of the hypothesis test from 2d, and given a significance of 0.05, we should
a) fail to reject the null. The data do not support the claim that the average traffic flow is
less than 9000 cars/day.
b) reject the null in favor of the alternative. The average traffic flow is less than 9000
cars/day.
