Problem 4 A Friday the 13th study provides data on traffic accident related emergency room admissions. The distributions of these counts from Friday the 6th and Friday the 13th are shown below for six such 6th 13th diff Mean 7.5 10.83 -3.33 SD 3.33 3.6 3.01 n 6 6 6 paired dates along with summary statistics. You may assume that conditions for inference are met. (a) Conduct a hypothesis test to evaluate if there is a difference between the average numbers of traffic accident related emergency room admissions between Friday the 6th and Friday the 13th. (b) Calculate a 95% confidence interval for the difference between the average numbers of traffic accident related emergency room admissions between Friday the 6th and Friday the 13th. (c) The conclusion of the original study states, \\Friday 13th is unlucky for some. The risk of hospital admission as a result of a transport accident may be increased by as much as 52%. Staying at home is recommended." Do you agree with this statement? Explain your reasoning
