IE 7610 Homework 4 Due March 31 1. A sample of peanut milk is analyzed and the percent protein extracted from the peanut milk samples are given below: 76.3 78.2 77.1 91.2 71.3 86.2 84.5 80.9 87.8 82.1 75.7 89.3 64.8 89.4 72.5 81.6 Will this data support a claim that the mean percent protein extracted exceed 80 percent? (Use confidence level of 95%). 2. A liquid dietary product claim that the use of the product for one month results in an average weight loss of at least 3 lbs. Eight people use the product and resulting weight data is given as follows: Initial Weight Final Weight 165 161 201 195 195 192 198 193 155 150 143 141 150 146 187 183
