Question
Suppose you are a manager for a carnival game at the local fair. You want to
estimate how many prizes you will need to have in stock to give out, based on
the number of tickets purchased before the fair begins. You examine the past 24
fair openings to make your regression model, and find the following
information.
(x − x)² = 791.5
Σe²
= = 223.1
and ŷ
=
294.21 +0.186x, where is the number of tickets purchased
before the fair begins, and ŷ is the predicted demand for prizes during the first
day of the fair. What is the standard error of the slope of the regression line?
