The textbook companies claim that book prices are actually dropping. A sample of 36 books were taken and we found that they had a mean price of $108. Assume the standard deviation for the population is $8. Using a significance level of 0.05, test the claim that the average textbook costs less than $100. Calculate the p-value.
