Question 2

A company has recorded data on the daily demand for its product (Y in thousands of units) and the unit price (X in hundreds of dollars). A sample of 15 days demand and associated prices resulted in the following data.

ΣX = 75

ΣY = 135

Σ (Y - )²= 100

Σ (Y -)(X -

a.	= 12.138 - 0.6277X
b.	R² = 0.3703
c.	F = 7.65; p-value is between .01 and .025; reject H_o and conclude that demand and unit price are related (critical F = 4.67)
