6- The areas covered by one gallon paint cans of certain brand are normally distributed. We purchased 8 of them from 8 different stores to maintain the randomness of our sample. We measured the coverage area each one gave. The coverages in square feet are as follows 344.3, 288.1, 328.7, 293.4, 374.6, 350.1, 325.1, 368.9 Construct a 95% confidence interval for the true average of coverage area of one gallon paint cans of this brand.
