A local group claims that the police issue at least 60 speeding tickets a day in their area. To prove their point, they randomly select 12 days. Their research yields the number of tickets issued for each day. The data are listed below. The sample standard deviation is 14.12. At α=0.01, test the group’s claim using p-values. 70 48 41 68 69 55 70 57 60 83 32 60 State the null hypothesis and alternative hypothesis. Calculate the t-statistic. What is the p-value? Is there enough evidence to support the group’s claim?
