Ans.
Y intercept, a = 10
Slope , b = 4
The least square regression line is
Y = 10 + 4 X
For the X = 2
The predicted value of Y is

Wide po is the intercept of the population regression line , is the slope of the population regression line s the error form, and the subscriptions over observations, ist.. For this, you collect data from a random sample of 250 people. After analyzing the data, you determine that the covariance between people's weight and the number of times they eat out in a month is 4.62 and the variance of the number of times people eat out in a month...
