Part A QuestionLet kids denote the number of children ever born to a woman and let educ denote years ofeducation for the woman. A simple model relating to the years of education isKids = Bo+ Bieduc + uWhere u in the unobserved error.(a) List three (3) factors are constrained in u?(b) Are the factors listed in (la) likely to be correlated with the level of education?(c) Will a simple regression analysis uncover the ceteris paribus effect of education onfertility?

A box office analyst seeks to predict opening weekend box office gross for movies. Toward this goal, the analyst plans to use online trailer views as a predictor. For each of the 66 movies, the number of online trailer views from the release of the trailer through the Saturday before a movie opens and the opening weekend box office gross (in millions of dollars) are collected and stored in the accompanying table. The least-squares regression equation for these data is Yi=−1.213+1.417Xiand the standard error of the estimate is SYX=19.599. Assume that the straight-line model is appropriate and there are no serious violations the assumptions of the least-squares regression model. Complete parts: a. At the 0.10 level of significance, is there evidence of a linear relationship between online trailer views and opening weekend box office gross? Determine the hypotheses for the test. b.
