Beckett Gillespie · 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

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
