Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 52.86. You want to test this claim. The null and alternative hypothesis in symbols would be: O Ho:p 52.86 o Ho:p 52.86 O Ho:p 2 52.86 H:p 52.86 H:p < 52.86 o Ho: u 52.86 H:p+52.86 The null hypothesis in words would be: The average price of textbooks in a sample is 5 52.86 O The average of price of all textbooks from the store is less than $ 52.86. O The average price of all textbooks from the store is $ 52.86 The average of price of all textbooks from the store is greater than $ 52.86, The proportion of all textbooks from the store that are less than 52.86 is equal to 50% of Based on a sample of 80 textbooks at the store, you find an average of 64.66 and a standard deviation of 17.
