Complete the following steps for the hypothesis test. Does Friday the 13th Change Human Behavior? Researchers obtained data kept by the British Department of Transport on the traffic flow through certain junctions of the M25 motorway in England. Assuming the flow of all traffic is normally distributed, perform the appropriate hypothesis test for determining whether the mean traffic flow is smaller for Friday the 13th compared with Friday the 6th, using the 0.5% level of significance.

State the level of significance. . For "" write "not equal". . For statements that are not the "claim", write "NA". in the box for claim. Ho: 14 0 Claim?: HI: / 0 Claim?: Tailed-Test: -tailed test Significance Level: a = Step 2: Check the requirements. Calculate the appropriate standardized test statistic (two decimal places) and P-value (4 decimal places). State the calculator function (Z-Test, T-Test, 1-PropzTest, 2-SampZTest, 2- SampTTest). . Remember that two-tailed tests have two standardized test statistics, always state both. Use the correct standard deviation variable, write NA in the remaining one. Calculator Function: Data/Stats?: Ho: List: Friday the 6th - Friday the 13th Standardized Tests Statistic(s): P-value = Step 3: Conclusion (make a decision) - your conclusion must indude supporting evidence. Conclusion: the Ho Supporting Evidence:
