Trials in an experiment with a polygraph include 98 results that include 22 cases of wrong results and 76 cases of correct results. Use a 0.05 significance level to test the claim that such polygraph results are correct less than 80% of the time. Identify the nullhypothesis, alternativehypothesis, teststatistic, P-value, conclusion about the nullhypothesis, and final conclusion that addresses the original claim. Use theP-value method. Use the normal distribution as an approximation of the binomial distribution.

The test statistic is z= ____ (ROUND TO TWO DECIMAL PLACES AS NEEDED.)

The P-value is ____ (ROUND TO FOUR DECIMAL PLACES AS NEEDED.)
