In the research study, 16 automobiles traveling at the same speeds are tested for stopping distances on wet pavement and then tested for stopping distances on dry pavement. On wet pavement, the standard deviation of stopping distances is 32 feet. On dry pavement, the standard deviation is 14 feet. a. At a 0.05 level of significance, do the sample data justify the conclusion that the variance in stopping distances on wet pavement is greater than the variance in stopping distances on dry pavement? What is the p-value? State the null and alternative hypotheses. Let the sample of stopping distances on wet pavement be represented by population 1. Ho : 62 - Select your answer - 02 Ha : 7 - Select your answer - Calculate the value of the test statistic (to 2 decimals) The p-value is - Select your answer - . Use Table 4 of Appendix B. What is your conclusion? Select your answer - v| that there is greater variability in stopping distances on wet pavement. b. What are the implications of your statistical conclusions in terms of driving safety recommendations? Drivers - Select your answer - v to allow |- Select your answer - |space between them and the car in front due to the - Select your answer - variability in stopping distances in wet conditions.
