1. write the claim as a mathematical statement? 2. choose the correct null and alternative hypothesis below? 3. identify the claim?

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $ 68.85. You want to test this claim.The null and alternative hypothesis in symbols would be: H0:p≥68.85H1:p<68.85 H0:p≤68.85H1:p>68.85 H0:μ=68.85H1:μ≠68.85 H0:μ≤68.85H1:μ>68.85 H0:p=68.85H1:p≠68.85 H0:μ≥68.85H1:μ<68.85 The null hypothesis in words would be: The average of price of all textbooks from the store is less than $$ 68.85. The average of price of all textbooks from the store is greater than $$ 68.85. The average price of textbooks in a sample is $$ 68.85 The proportion of all textbooks from the store that are less than 68.85 is equal to 50% The average price of all textbooks from the store is $$ 68.85 Based on a sample of 90 textbooks at the store, you find an average of 67.05 and a standard deviation of 15.6.The point estimate is:  (to 3 decimals)The 95 % confidence interval (use z*) is:  ______ to  _____(to 3…

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.
