Nationwide, it is estimated that 40% of service stations have gas storage tanks that leak to some extent. California is trying to lessen that trend. We want to assess the effectiveness of their efforts by seeing if the percentage of service stations whose tanks leak has decreased. To do this, we randomly sample 27 service stations in California and determine whether there is any evidence of leakage. In our sample, only 7 of the station exhibit any leakage. Is there evidence that their efforts have paid off… that stations are showing less leakage?
