. Question 5 Suppose that BC financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 99.92. You want to test this claim. The null and alternative hypothesis in symbols would be: O Ho:p = 99.92 H1 :p # 99.92 O Ho:p > 99.92 H1 :p 99.92 O Ho:p 99.92 O Ho: M = 99.92 H1: u # 99.92 The null hypothesis in words would be: O The average price of all textbooks from the store is $ 99.92 The average of price of all textbooks from the store is less than $ 99.92. The proportion of all textbooks from the store that are less than 99.92 is equal to 50% The average of price of all textbooks from the store is greater than $ 99.92. The average price of textbooks in a sample is $ 99.92 Based on a sample of 140 textbooks at the store, you find an average of 105.92 and a standard deviation of 12.8. The point estimate is: (to 3 decimals) The 99 % confidence interval (use z*) is: to (to 3 decimals) Based on this we: O Reject the null hypothesis O Fail to reject the null hypothesis
