Null hypothesis: The mean price of restaurant meal is the same as fixing a comparable meal at home.

Alternate hypothesis: The mean price of restaurant meal is less than fixing a comparable meal at home.

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 the population parameter that negates the null hypothesis and is accepted if the null hypothesis is proven false.
