Trials in an experiment with a polygraph include 98 results that include 23cases of wrong results and 75 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 asneeded.)

Identify theP-value.

Determine if the test isleft-tailed, right-tailed, ortwo-tailed.

Identify the conclusion for this hypothesis test.
