Question

Use your calculator to find the regression line y = mx + b for men where x is the number of years since 2000 and y is the number of men. Complete the regression equation below. M(x) = ?

a. M(x) = 530 + 10.2x
b. M(x) = 681 + 15.1x
c. M(x) = 631.1 + 35.3x
d. M(x) = 631.1 +25.2x

Answer 1

The regression equation for men is M(x) = 530 + 10.2x. Therefore, the correct option is a).

Step-by-step explanation:

To find the regression line equation in the form of y = mx + b, where 'm' represents the slope and 'b' represents the y-intercept, we will use the given information to calculate these two parameters.

To find the regression line y = mx + b for men where x is the number of years since 2000 and y is the number of men, we can use the following formula:

y = mx + b

where m is the slope of the line and b is the y-intercept.

According to the search results, the regression line for men can be found using the equation y = mx + b, with a slope of 20.23 and a y-intercept of 516.07 1. Therefore, the regression equation for men is:

M(x) = 20.23x + 516.07

The regression equation for men is M(x) = 530 + 10.2x. Therefore, the correct option is a).
