Using the t-test to test the claim, interpret your decision in the context of the original claim, assume the population is normally distributed.

A fitness magazine advertise that the mean monthly cost of joining a health club is $25.00. You work for a consumer advocacy group and are asked to test the claim. You find that a random sample of 18 clubs has a mean monthly cost of $26.25 and a standard deviation of $3.23.At a=0.10, do you have enough evidence to reject theadvertisement claim?

can I have step by step on coming up with the answer?
