Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 96.54. You want to test this claim. The null and alternative hypothesis in symbols would be: O Ho:H = 96.54 H1:p # 96.54 O Ho:p 2 96.54 H1:p 96.54 O Ho:µ > 96.54 H : µ 96.54 O Ho:p= 96.54 H:p# 96.54 The null hypothesis in words would be: O The proportion of all textbooks from the store that are less than 96.54 is equal to 50% O The average of price of all textbooks from the store is less than $ 96.54. O The average price of all textbooks from the store is $ 96.54 O The average price of textbooks in a sample is $ 96.54 O The average of price of all textbooks from the store is greater than $ 96.54. Based on a sample of 200 textbooks at the store, you find an average of 92.14 and a standard deviation of 19.8.
