Questionn this exercise, test $$H_{0}: p=0.5 \text { vs } H_{a}: p>0.5$$ with $\hat{p}=0.55$ for different sample sizes. In parts (a)-(c), use StatKey or other technology to find the $p$-value. Click here to access StatKey. (a) $\hat{p}=\frac{55}{100}=0.55$
Round your answer to two decimal places. $p$-value $=$ $\square$
Are the results significant at the $5 \%$ level? (b) $\hat{p}=\frac{275}{500}=0.55$
Round your answer to three decimal places. $p$-value $=$ $\square$ Are the results significant at the $5 \%$ level? $\square$ (c) $\hat{p}=\frac{550}{1000}=0.55$
Round your answer to three decimal places. $p$-value $=$ $\square$ i
Are the results significant at the $5 \%$ level? $\square$ (d) Which provides the strongest evidence for the alternative hypothesis? $\square$
