Problem 7. An experiment was conducted to study the eeet of temperature and type of oven on the life of a particular component being tested. Four types of ovens and 3 temperature levels were used in the experiment. Twenty-four pieces were assigned randomly, 2 to each combination of treatments, and the following results recorded. Temperature Oven (Degrees) 01 03 03 O4 500 227 214 225 260 221 259 236 229 550 187 181 232 246 208 179 198 273 600 174 198 178 206 202 194 213 219 Using a 0.05 level of significance, test the hypothesis that a. the type of even and temperature do not interact; b. different temperatures have no effect on the life of the component; c. different ovens have no effect on the life of the component
