Question

PLEASE HELP REALLY IMPORTANT The price of a container of laundry detergent (in dollars)

varies with the size (x) of the container (in pounds). The
variables have a strong linear correlation and the equation
for the least squares regression line is y^= 0.86x + 0.52
Based on the regression equation, which is the best
prediction for the price of a 70-pound container of detergent?
$70
$86
$65
$60

Answer 1

$60

Explanation:

Based on the regression equation, the best prediction for the price of a 70-pound container of detergent can be found by substituting x = 70 into the equation:

y^ = 0.86x + 0.52

y^ = 0.86(70) + 0.52

y^ = 60.2 + 0.52

y^ ≈ $60.72

Therefore, the best prediction for the price of a 70-pound container of detergent is approximately $60.72. However, since we are dealing with prices, it is reasonable to round this value to the nearest dollar, which would be $61. But since none of the answers are 61 it would be $60.
