Question

Suppose that BC financial aid alots a textbook stipend by claiming that the average textbook at BC bookstore costs $62.74. You want to test this claim. The null and alternative hypothesis in symbols would be: O Hop=62.74 H:p +62.74 OH: < 62.74 H: > 62.74 OHO:n = 62.74 H:A#62.74 OHO: > 62.74 Hu< 62.74 OH :p < 62.74 H:p> 62.74 The null hypothesis in words would be: O The average price of textbooks in a sample is $ 62.74 The average of price of all textbooks from the store is greater than $ 62.74. The proportion of all textbooks from the store that are less than 62.74 is equal to 50% O The average of price of all textbooks from the store is less than $ 62.74. O The average price of all textbooks from the store is $ 62.74 Based on a sample of 110 textbooks at the store, you find an average of 73.74 and a standard deviation of 10 The point estimate is: (to 3 decimals) to (to 3 The 95% confidence interval (use 2*) is: decimals) Based on this we O Fail to reject the null hypothesis O Reject the null hypothesis
