O Ho: PI = P2 versus H: PI < P O Ho: PI + P2 versus H P = P2 O Ho: PI = P2 versus H Pi > P2 %3! SOLVE: Assume the samples can be thought of as an SRS. We can conduct a hypothesiss test since there are more than five successes (corrctly identified the pains) and more than five failures in cach sample. Calculate i , Þy, and p. (Enter your answers rounded to four decimal places.) Compute the z test statistic. (Enter your answer rounded to four decimal places.) Using the software of your choice, calculate the one-sided P-value for the null hypothesis. (Enter your answer rounded to three decimal places.) CONCLUDE: Which conclusion is correct? O There is enough evidence to conclude that blacking out the mouth region reduces a subject's ability to correctly match dog-owner pairs. There is not enough evidence to conclude that blacking out the mouth region reduces a subject's ability to correctly match dog-owner pairs. (b) Is there evidence that blacking out the eyes reduces a subject's ability to choose the sheet which correctly matches the dogs and their owners? STATE: We want to know if blacking out the eye region reduces a subject's ability to correctly match the dog-owner pairs.
