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

The data are as follows: Temperature Copper Content Warping 50 40 17 50 40 20 50 60 16 50 60 21 50 80 24 50 80 22 50 100 28 50 100 27 75 40 12 75 40 9 75 60 18 75 60 13 75 80 17 75 80 12 75 100 27 75 100 31 100 40 16 100 40 21 100 60 18 100 60 21 100 80 25 100 80 23 100 100 30 100 100 23 125 40 21 125 40 17 125 60 23 125 60 21 125 80 23 125 80 22 125 100 29 125 100 31 a) Analyze if temperature, copper contents and their interaction significantly affect the warping b) Describe how temperature, copper contents and their interaction affect the warping c) If low warping is desired, what copper content would you specify? Given that temperature can not be easily adjusted....
