Essay

You run a regression analysis and receive the following results:
$\begin{array}{ll}\hline\text { Multiple R } & .39429 \\\text { R Square } & .15547 \\\text { Adjusted R Square } & .14964 \\\text { Standard Error } & .44416\\\hline\end{array}$

$\text { Analysis of Variance }$
$\begin{array}{lccc}\hline& D F & \text { Sum of Squares } & \text { Mean Square } \\\hline \text { Regression } & 1 & 5.26588 & 5.26588 \\\text { Residual } & 145 & 28.60536 & .19728 \\\hline\end{array}$

$F=26.69262 \quad \text { Signif } F=.0000$

$\begin{array}{lcccc}\hline\text { Variable } & \text { Coefficients } & \text { Standarderror } & t \text { Stat } & P \text {-value } \\\hline \mathrm{X} \text { Variable } 1 & 11.0300 & .021000 & 5.166 & .0000 \\\text { Intercept } & 8833.0700 & .090000 & 9.751 & .0000\end{array}$

Required:
A. What is the fixed cost in this regression analysis?
B. What is the variable cost per unit?
C. Prepare the cost equation based upon these results.
D. Does this regression equation 'fit' the data well? What information did you examine to answer this question?

Understand the relationship between benefit-cost ratio and return on investment in evaluating training programs.

Comprehend the objectives and outcomes of specific training programs, such as those aimed at reducing equipment downtime and improving product quality.

Recognize the significance of using both internal and external experts when estimating training benefits.

Calculate training program utility and interpret its implications for decision making.

Definitions:

Gastric Glands

Glands in the wall of the stomach; contain cells that secrete hydrochloric acid, intrinsic factor, and pepsinogen, the precursor of the enzyme pepsin.

Parietal Cells

Cells in the lining of the stomach that produce hydrochloric acid and intrinsic factor, crucial for digestion and B12 absorption.

Goblet Cells

Goblet cells are specialized epithelial cells found in the respiratory and digestive tracts, secreting mucus to lubricate and protect the mucous membranes.

Tube-Within-a-Tube

A body plan characteristic of many animals, where the inner tube represents the digestive tract and the outer tube the body wall, with a cavity in between.
