You are testing the claim that the mean GPA of night students is different from the mean GPA of day students. A sample of 25 night students and 27 day students and their GPA's are recorded below. Test the claim using a 5% level of significance. Assume the population variances are unequal and that GPAS are normally distributed. Give answers to 4 decimal places. GPA-Night GPA-Day 3.27 2.97 3.23 3.18 3.45 2.85 3.46 3.15 3.4 3.1 3.39 3.38 3.3 3.51 3.41 3.15 2.94 3.34 3.2 3.02 3.12 3.13 3.55 3.03 3.09 2.43 3.43 3.18 2.91 3.09 2.91 3.23 2.75 3.44 3.29 3.06 3.5 3.28 3.04 3.23 3.01 3.38 3.46 2.93 2.77 2.99 2.47 3.92 3.35 3.35 2.83 2.84 What are the correct hypotheses?

"Durable press" cotton fabrics are treated to improve their recovery from wrinkles after washing. "Wrinkle recovery angle" measures how well a fabric recovers from wrinkles. Higher is better. Here are data on the wrinkle recovery angle (in degrees) for a random sample of fabric specimens. Assume the populations are approximately normally distributed with unequal variances. A manufacturer believes that the mean wrinkle recovery angle for Hylite is better. A random sample of 25 Permafresh (group 1) and 20 Hylite (group 2) were measured. Test the claim using a 5% level of significance. Permafresh 120 154 112 140 114 139 133 149 128 116 142 154 104 130 159 143 126 110 115 124 144 128 151 119 150 Hylite 147 129 141 143 142 139 141 147 148 142 153 158 139 140 140 132 138 149 137 137
