question 126

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, which is the correct null hypothesis for testing whether the number of customers who make a purchase affects weekly sales? a) $H _ { 0 } : \beta _ { 0 } = 0$
b) $H _ { 0 } : \beta _ { 1 } = 0$
c) $H _ { 0 } : \mu = 0$
d) $H _ { 0 } : \pi = 0$
