Suppose we are testing ${H}_{0}:p=.20$ vs ${H}_{a}:p>>.20$ and TS=2.34. What is the p-value?

Given: (TS=test statistic z)
${H}_{0}:p=0.20$
${H}_{a}:p>0.20$
z=2.34
The P-value is the probability of obtaining the value of the test statistic, or a value more extreme, when the null hypothesis is true. Determine the P-value using the normal probability table in the appendix.
P=P(Z<2.34)=1-P(Z>2.34)=1-0.9904=0.0096
