Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 60.92. You want to test this claim.The null and alternative hypothesis in symbols would be: a) H0:p≤60.92H1:p > 60.92 b) H0:μ=60.92; H1:μ≠60.92 c) H0:μ ≥ 60.92; H1:μ < 60.92 d) H0:μ ≤ 60.92; H1:μ > 60.92 e) H0:p≥60.92; H1:p<60.92 f) H0:p=60.92; H1:p≠60.92 The null hypothesis in words would be: The average price of all textbooks from the store is $$ 60.92 The average price of textbooks in a sample is $$ 60.92 The average of price of all textbooks from the store is less than $$ 60.92. The proportion of all textbooks from the store that are less than 60.92 is equal to 50% The average of price of all textbooks from the store is greater than $$ 60.92. Based on a sample of 110 textbooks at the store, you find an average of 65.72 and a standard deviation of 17.The point estimate is: ______ (to 3 decimals)The 95 % confidence interval (use z*) is: _____ to ______…
