QUESTION 9Consider the simple linear regression model, y = Bo + B₁x + u. Which of the following statements is correct?The zero conditional mean assumption, E(u|x) = 0, includes the assumption that the average value of u in the population is zero: E(u)= 0.a.The zero conditional mean assumption, E(u|x) = 0, includes the assumption that the average value of u does not depend on the valueof x: E(ulx) = E(u).C.The zero conditional mean assumption implies that population regression function (PRF) is a linear function of x: E(ylx) = Bo + B₁x,indicating that a one-unit increase in x changes the expected value of y by the amount ³₁.d. Options (a), (b) and (c) are correctO e. Options (a) and (c) are correct

The image contains two graphs typical of the analysis of a simple linear regression model. It can be stated that: a. The variance of the errors seems constant b. The errors do not come from a normal distribution c. The linear model does not seem appropriate d. The residuals are close to the line and therefore there is normality in the data. Why? Thanks
The difference between a regression weight and a beta weight is: A regression weight assumes linearity. A beta weight is for the population while a regression weight is for the sample. A regression weight is less biased. A beta weight is a standardized regression weight.

A study examined the eating habits of 20 children at a nursery school. The variables measured for each child included: calories (the number of calories eaten at lunch), time (the time in minutes spent eating lunch), and sex (male=1, female=0). A multiple linear regression model using Y = calories, X1 = time, and X2 = sex led to the following model: y=547.65-2.85x1+10.67x2 For two children who spend the same amount of time eating, one male and one female, which child is predicted to consume more calories and by how much?
