Suppose that Brooklyn College financial aid allots a textbook stipend by claiming that the average textbook at BC bookstore costs $63.26. You want to test this claim. The null and alternative hypothesis in symbols would be: Ο Ho: μ = 63.26 Η: μ # 63.26 O Ho:p ≤ 63.26 H₁:p> 63.26 Ho: μ ≥ 63.26 H:μ 63.26 H₁:p 63.26 O Ho:p = 63.26 H₁:p 63.26 The null hypothesis in words would be: The average price of textbooks in a sample is $63.26 O The proportion of all textbooks from the store that are less than 63.26 is equal to 50% The average price of all textbooks from the store is $63.26 O The average of price of all textbooks from the store is greater than $63.26. O The average of price of all textbooks from the store is less than $63.26. Based on a sample of 170 textbooks at the store, you find an average of 67.66 and a standard deviation of 28.2.
