Professors collected data consisting of eye color and gender of statistics students. Among 912 male students, 276 had blue eyes. Among 1102 female students, 372 had blue eyes. Use a 0.01 significance level to test the claim that the proportions of blue eyes are the same for males and females. Complete parts (a) through (c) below. Consider the first sample to be the sample of males and the second sample to be the sample of females. O D. Ho: P₁ = P₂ H₁: P₁ P₂ Identify the test statistic. Z= -1.67 (Round to two decimal places as needed.) Identify the P-value. P-value = 0.095 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? O E.

. Myers-Briggs: Actors Isabel Briggs Myers was a pioneer in the study of personality types. The following information is taken from MBTI Manual: A Guide to the Development and Use of the Myers-Briggs Type Indicator by Myers and McCaulley (Consulting Psychologists Press). In a random sample of 62 professional actors, it was found that 39 were extroverts. Let p represent the proportion of all actors who are extroverts. Find a point estimate for p. Find a 95% confidence interval for p. Give a brief interpretation of the meaning of the confidence interval you have found.
