A city police department wants to know if the new law enacted to curb traffic violations by its citizens has been effective in decreasing the number of car accidents. They randomly sampled a week, before and after the law was passed and counted the number of accidents for each day in each week. Here are the results: e. Find the value of the t-statistic and number of degrees of freedom accordingly? f. Give a conclusion of your hypothesis test at the 5% significance level. g. At the 1% significance level, does your conclusion change?
