Below. The correct null and alternative hypotheses for testing the regression coefficient of Price

A) $H_{0}: \beta_{\mathrm{P}} \neq 0$ vs. $\mathrm{H}_{\mathrm{A}}: \beta_{\mathrm{P}}=0$
B) $\mathrm{H}_{0}: \beta_{\mathrm{P}} \geq 0$ vs. $\mathrm{H}_{\mathrm{A}:}: \beta_{\mathrm{P}}<0$
C) $\mathrm{H}_{0}: \beta_{\mathrm{P}} \leq 0$ vs. $\mathrm{H}_{\mathrm{A}}: \beta_{\mathrm{P}}>0$
D) $\mathrm{H}_{0:} \beta_{\mathrm{P}}=0$ vs. $\mathrm{H}_{\mathrm{A}}: \beta_{\mathrm{P}} \neq 0$
E) $\mathrm{H}_{0}$ : The regression is not significant vs. $\mathrm{H}_{\mathrm{A}}$ : The regression is significant.
