Question

Because the number of pepperoni slices is related to the surface area of the pizza, and surface area is related to the square of the diameter, the students performed a regression analysis of y = the number of pepperoni slices and x = diameter2. Which is the equation of the least-squares regression line that the students calculated?

Answer 1

b on edge

Answer 2

Explained below.

Explanation:

The least square regression line is: Y = a + bX, where a = intercept (constant), b = slope co-efficient, X = dependent variable and Y = dependent variable.

The components of the least square regression line are the intercept and slope.

The least square regression line is used to predict the value of the dependent variables when the value of the independent variable is known.

In this case a least square regression line will be formed to determine the the number of pepperoni slices is related to the surface area of the pizza.
