Suppose We Are Testing Ho: P=.20 Vs Ha: P Does Not Equal .20 And Ts=2.34. What Is The P-value?

Suppose we are testing Ho: p=.20 vs Ha: p>.20 and TS=2.34. What is the p-value? Answer Given (TS = test statistic z) 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 …
