Multiple Choice

TABLE 13-2
A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below:
$$\begin{array} { l l c } \hline \text { City } & \text { Price } ( \$ ) & \text { Sales } \\\hline \text { River Falls } & 1.30 & 100 \\\text { Hudson } & 1.60 & 90 \\\text { Ellsworth } & 1.80 & 90 \\\text { Prescott } & 2.00 & 40 \\\text { Rock Elm } & 2.40 & 38 \\\text { Stillwater } & 2.90 & 32 \\\hline\end{array}$$
-The sample correlation coefficient between X and Y is 0.375. It has been found out that the p- value is 0.744 when testing H0 : ? = 0 against the one- sided alternative H0 : ? < 0. To test H0 : ? = 0 against the two- sided alternative H0 : ?? 0 at a significance level of 0.2, the p- value is

A) (1 - 0.744) (2) .
B) (0.744) (2) .
C) 0.744/2.
D) 1 - 0.744.
