In Testing the Hypotheses $$H _ { 0 } : p = 0.50$$

question 9

Short Answer

In testing the hypotheses: $$H _ { 0 } : p = 0.50$$ $$H _ { 1 } : p \neq 0.50$$ , at the 10% significance level, if the sample proportion is 0.56, and the standard error of the sample proportion is 0.025, the appropriate conclusion is: $\begin{array}{|l|l|}\hline A&\text { to reject } H_{0} \\\hline B&\text { not to reject } H_{0} \\\hline C&\text { to reject } H_{1} \\\hline D&\text { to reject both } H_{0} \text { and } H_{1} \text {. } \\\hline\end{array}$
