Significance tests $\mathrm{A}$ test of $H_{0} : p=0.65$ against $H_{a} : p<0.65$ has test statistic $z=-1.78$ (a) What conclusion would you draw at the 5$\%$ significance level? At the 1$\%$ level? (b) If the alternative hypothesis were $H_{a} : p \neq 0.65$ what conclusion would you draw at the 5$\%$ significance level? At the 1$\%$ level?

Step 1
78 for the test of $H_{0} : p=0.65$ against $H_{a} : p<0.65$. Given that z = -1.78, the p-value is found to be 0.0375. ** Show more…

Significance tests $A$ test of $H_{0}: p=0.5$ versus $H_{a}: p>0.5$ has test statistic $z=2.19$ (a) What conclusion would you draw at the $5 \%$ significance level? At the $1 \%$ level? (b) If the alternative hypothesis were $H_{a}: p \neq 0.5,$ what conclusion would you draw at the $5 \%$ significance level? At the $1 \%$ level?

Significance tests $A$ test of $H_{0} : p=0.5$ versus $H_{a} :$ $p>0.5$ has test statistic $z=2.19$ . (a) What conclusion would you draw at the 5$\%$ significance level? At the 1$\%$ level? (b) If the alternative hypothesis were $H_{a} : p \neq 0.5$ what conclusion would you draw at the 5$\%$ significance level? At the 1$\%$ level?
Testing a Claim
Tests about a Population Proportion
Consider the following hypothesis test: $$\begin{array}{l}{H_{0} : \mu=100} \\ {H_{\mathrm{a}} : \mu \neq 100}\end{array}$$ A sample of 65 is used. Identify the $p$ -value and state your conclusion for each of the following sample results. Use $\alpha=.05 .$ a. $\overline{x}=103$ and $s=11.5$ b. $\overline{x}=96.5$ and $s=11.0$ c. $\overline{x}=102$ and $s=10.5$
