For a test of $\displaystyle {H}_{{0}}$ : $\displaystyle {p}={0.75}$, the sample proportion is $\displaystyle \hat{{p}}=$0.76 based on a sample size of 50. Use this information to complete parts (a) through (c) below.

a. $\displaystyle {z}$ = (Round to two decimal places.)

b. Find the $\displaystyle {P}$-value if the alternative hypothesis is $\displaystyle {H}_{{a}}$ : $\displaystyle {p}<{0.75}$
$\displaystyle {P}$-value = (Round to four decimal places.)

c. Does the $\displaystyle {P}$-value in (b) give much evidence against $\displaystyle {H}_{{0}}$?
