Does Octane matter? Some people believe that different octane gasoline result in different miles per gallon in a vehicle. The following is a sample of 11 cars. Each person was asked to drive his/her car for as long as a 10 gallon tank would take them. The mileage was recorded below. Person Miles on 87 Octane Miles on 92 Octane 1 234 237 2 257 238 3 243 229 4 215 224 5 114 119 287 297 7 315 351 8 229 241 9 192 186 10 204 209 11 547 562 Do the data support that different octanes produce different miles per gallon, at the a =.02 level of significance? a) Express the null and alternative hypotheses in symbolic form for this claim. Assume d = 92 octane - 87 octane. Enter != for +. b) What is the significance level? c) What is the test statistic? Round to 3 decimal places. 6.
