Answer:
The distance is 4.
Step-by-step explanation:
The shortest distance from the point (4,2) to the line y=-2, in this case, would be a straight line perpendicular to y=-2.
For each and every value of "x" on the line, y = -2. The shortest distance occurs at y(4) = - 2.
At this point the distance is:
The distance is 4.
Answer:
The predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
Step-by-step explanation:
The least square regression line is used to predict the value of the dependent variable from an independent variable.
The general form of a least square regression line is:
Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>α</em> = intercept
<em>β</em> = slope
The regression line to predict the life expectancy of men in a country from the life expectancy of women in that country is:
Compute the life expectancy of men in a country in which the life expectancy of women is 70 years as follows:
Thus, the predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
