question 99

Short Answer

SCENARIO 12-10
The management of a chain electronic store would like to develop a model for predicting the weekly sales (in thousands of dollars) for individual stores based on the number of customers who made purchases.A random sample of 12 stores yields the following results: $$\begin{array} { | l | c | } \hline \text { Customers } & \begin{array} { l } \text { Sales } \\\text { (Thousands of } \\\text { Dollars) }\end{array} \\\hline 907 & 11.20 \\\hline 926 & 11.05 \\\hline 713 & 8.21 \\\hline 741 & 9.21 \\\hline 780 & 9.42 \\\hline 898 & 10.08 \\\hline 510 & 6.73 \\\hline 529 & 7.02 \\\hline 460 & 6.12 \\\hline 872 & 9.52 \\\hline 650 & 7.53 \\\hline 603 & 7.25 \\\hline\end{array}$$
-Referring to Scenario 12-10, what is the value of the F test statistic when testing whether the number of customers who make purchases is a good predictor for weekly sales?

Definitions:

S Phase

Stage in interphase of the cell cycle during which DNA and other chromosomal constituents are synthesized. Compare with G1 phase and G2 phase.

Metaphase

A stage of cell division where chromosomes line up at the cell's equator before being separated into each of the two new cells.

Prophase

The first stage of cell division in both mitosis and meiosis, characterized by the condensation of the chromatin and the formation of the mitotic spindle.

Meiosis

A form of cell division in sexually reproducing organisms that reduces the chromosome number by half, producing four haploid cells, each genetically distinct from the parent cell that gave rise to them.
