The deflection temperature under load for two different types of plastic pipe is being investigated. Two random samples of 15 pipe specimens are tested, and the deflection temperatures observed are as follows (in °F): Type 1 208 190 207 189 196 195 209 187 191 215 194 212 196 180 207 Type 2 180 200 209 204 183 179 188 203 200 195 201 191 192 206 195

The deflection temperature under load for two different types of plastic pipe is being investigated. Two random samples of 15
pipe specimens are tested, and the deflection temperatures observed are as follows (in °F):
Type 1 208 190 207 189 196 195 209 187 191 215 194 212 196 180 207
Type 2 180 200 209 204 183 179 188 203 200 195 201 191 192 206 195
X Your answer is incorrect.
(a) Do the data support the claim that the deflection temperature under load for type 1 pipe exceeds that of type 2? In
reaching your conclusions, use a = 0.05. Suppose that the hypotheses are Ho: 41 – 42 = 0versus H1: 41 - H2 > 0.
Calculate a P-value. Use lower and upper bounds for the P-value.
