The number of calories in a 12-ounce serving of randomly-selected regular and lite beers is listed. Find the critical value to test that the mean number of calories for lite beers is significantly more than that for the regular beers? Use. Assume the variables are approximately normally distributed. Use the level of significance=0.02. Sample1=Regular Sample2=Lite Regular: 142 164 95 108 154 168 122 160 176 111 113 176 Lite: 115 108 91 75 123 91 34 129 37
