trials in an experiment with a polygraph include 98 results that include 23 cases of wrong results and 75 cases of Craig results. Use a 0.01 significance level to test the claim that such polygraph results are correct less than 80% of the time. Identify the no hypothesis, alternative hypothesis, test tested, P value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P value method. Use a normal distribution as an approximation of the binomial distribution.

Researchers measured skulls from different time periods in an attempt to determine whether interbreeding of cultures occurred. Results are given below. Assume that both samples are independent simple random samples from populations having normal distributions. Use a 0.05 significance level to test the claim that the variation of maximal skull breadths in 4000 B.C. is the same as the variation in A.D, 150. 4000 B.C. 30 131.91 mm 5.18 mm A.D. 150 30 136.44 mm 5.36 mm O B.
