#32). Due to bartleby’s guidelines my tutor didn’t finish my problem. Please do the ones that are blank. Both pictures are the same problem.
Electric vehicles are often categorized by the range of miles that can be travelled on a single battery
charge, since charging stations are not yet widespread in the United States.
The latest model of a certain brand of electric car is reported to have an average range of 222 miles.
An auto industry journalist would like to verify this claim, since she believes that the true range of the car
may be less than 222 miles. The journalist selected and tested a random sample of 143 cars of this model
and found that the average range of the sample was 211.9 miles with a standard deviation of 35.8 miles.
Apply the p-value method to test the hypothesis that the average range of this electric car model is less
than 222 miles, using a =
0.005.
State the null and alternative hypothesis for this test.
