An auto rental firm is using 15 identical motors that are adjusted to run at a fixed speed to test 3 different brands of gasoline. Each brand of gasoline is assigned to exactly 5 of the motors. Each motor runs on 10 gallons of gasoline until it is out of fuel. The following represents the total mileages obtained by the different motors: Gas 1: 220 251 226 246 260 Gas 2: 244 235 232 242 225 Gas 3: 252 272 250 238 256 a) Calculate the sum of squared deviation within and between each of type of gasoline used, for their mileages obtained.

Transcribed Image Text:Question 4
An auto rental firm is using 15 identical motors that are adjusted
to run at a fixed speed to test 3 different brands of gasoline. Each
brand of gasoline is assigned to exactly 5 of the motors. Each
motor runs on 10 gallons of gasoline until it is out of fuel.
The following represents the total mileages obtained by the
different motors:
Gas 1: 220 251 226 246 260
Gas 2: 244 235 232 242 225
Gas 3: 252 272 250 238 256
a) Calculate the sum of squared deviation within and between each
of type of gasoline used, for their mileages obtained.
Transcribed Image Text:c) Test the hypothesis that the average mileage obtained is not
affected by the type of gas used. Use the 5% level of significance.
