Question

I need help with this problem.

Some people believe that different octane gasoline result in different miles per gallon in a vehicle. The following data is a sample of 11 people which were asked to drive their car only using 10 gallons of gas and record their mileage for each 87 Octane and 92 Octane. Person 1 2 3 4 5 لیا 6 7 8 9 10 11 Miles with 87 Octane 234 257 243 215 114 287 315 229 192 204 547 Miles with 92 Octane Ho : u d H₁: Pa #0 237 238 229 224 119 297 351 =0 241 186 209 Do the data support that different octanes produce different miles per gallon at the a = 0.02 level of significance? Note: A normal probability plot of difference in car mileage between Octane 87 and Octane 92 indicates the population could be normal and a boxplot indicated no outliers. 562 a. Express the null and alternative hypotheses in symbolic form for this claim. Assume µā = µ₁ − µ2, where ₁ is the population mean mileage for Octane 87 and µ is the mean mileage for Octane 92. b.
