Question
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
H:p> 52.86
o Ho:p < 52.86
H:p> 52.86
O Ho:p 2 52.86
H:p < 52.86
O Ho p 52.86
H:p 52.86
O Ho: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
