Identify the regression analyses necessary for testing this initial model. The following exercises utilize the path model depicted below as well as the data set country-c.sav. Specifically, the variables of Indocs (z₁), lngdp (z₂), deathrat (z₃), birthrat (z₄), and lifeexpf (z₅) will be utilized.### Path Diagram Explanation- **Variables:** - $ z_1 $: Indocs - $ z_2 $: lngdp - $ z_3 $: deathrat - $ z_4 $: birthrat - $ z_5 $: lifeexpf- **Path Coefficients:** - $ p_{31} $: Path from $ z_1 $ to $ z_3 $. - $ p_{42} $: Path from $ z_2 $ to $ z_4 $. - $ p_{52} $: Path from $ z_2 $ to $ z_5 $. - $ p_{53} $: Path from $ z_3 $ to $ z_5 $. - $ p_{54} $: Path from $ z_4 $ to $ z_5 $.- **Correlations and Errors:** - $ r_{12} $: Correlation between $ z_1 $ and $ z_2 $. - Errors for each variable ($ e_3 $, $ e_4 $, $ e_5 $) are depicted with arrows pointing towards $ z_3 $, $ z_4 $, and $ z_5 $ respectively. These represent the unexplained variances in those variables.

An oil exploration company wants to develop a statistical model to predict the cost of drilling a new well. One of the many variables thought to be an important predictor of the cost is the number of feet in depth that the must be drilled to create the well. Consequently, the company decided to fit the simple linear regression model, where y = cost of drilling the new well (in $thousands) and x = number of feet drilled to create the well. Using data collected for a sample of n=83 wells, the following results were obtained: = 10.5 + 16.20x Give a practical interpretation of the estimate of the slope of the least squares line.

A local University conducted a survey of over 2,000 MBA alumni to explore the issue of work-life balance. Each participant received a score ranging from 0 to 100, with lower scores indicating a higher imbalance between work and life. A sample of the data is available below. Let x = average number of hours worked per week and y=work-life balance scale score for each MBA alumnus.

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. A linear regression was performed on these data, and the result is the linear regression equation Yi=−1.254+1.3968Xi. Complete parts (a) through (d). a. Determine the coefficient of determination,r2,and interpret its meaning. b. Determine the standard error of the estimate. c. How useful do you think this regression model is for predicting opening weekend box office gross? d. Can you think of other variables that might explain the variation in opening weekend box office gross?
A real estate analyst has developed a multiple regression line, y = 60 + 0.068 x1 – 2.5 x2, to predict y = the market price of a home (in $1,000s), using two independent variables, x1 = the total number of square feet of living space, and x2 = the age of the house in years. With this regression model, the predicted price of a 10-year old home with 2,500 square feet of living area is __________. $205.00 $200,000.00 $205,000.00 $255,000.00
