Answer:

Null hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is 40,000 miles.

Alternate hypothesis: The average life expectancy of tires produced by the Whitney Tire Company is greater than 40,000 miles.

Explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.

An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
