Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $$ 76.13. You want to test this claim. The null hypothesis in words would be: The proportion of all textbooks from the store that are less than 76.13 is equal to 50% The average of price of all textbooks from the store is greater than $$ 76.13. The average price of all textbooks from the store is $$ 76.13 The average price of textbooks in a sample is $$ 76.13 The average of price of all textbooks from the store is less than $$ 76.13. Based on a sample of 120 textbooks at the store, you find an average of 83.33 and a standard deviation of 10. The point estimate is: (to 3 decimals) The 95 % confidence interval (use z*) is: to (to 3 decimals)
