We are comparing the mean prices of fiction and non-fiction books.
We sampled 60 fiction books, and got a sample mean of $39 and a sample standard deviation 16.
We sampled 50 non-fiction books, and got a sample mean of $36 and a sample standard deviation 13.
Does the data provide sufficient evidence to conclude that fiction books cost more on average than non-fiction books?

P-value =

(yes/no)= , because we= ,H0 , and the conclusion is=
