Question

An automobile manufacturer claims that the average gas mileage of a new model is 35 miles per gallon (mpg). A consumer group is skeptical of this claim and thinks the manufacturer may be overstating the average gas mileage. If µ represents the true average gas mileage for this new model, which of the following gives the null and alternative hypotheses that the consumer group should test?

Answer 1

Null hypothesis: The average gas mileage for the new model is 35 miles per gallon

Alternate hypothesis: The average gas mileage for the new model is less than 35 miles per gallon

Step-by-step explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing

An alternate hypothesis is also a statement from a population parameter that negates the null hypothesis and is true if the null hypothesis is proven to be false
