In a study of red/green color blindness, 900 men and 2950 women are randomly selectedand tested. Among the men, 82 have red/green color blindness. Among the women, 9 havered/green color blindness. Test the claim that men have a higher rate of red/green color blindness.(Note: Type "p_m" for the symbol Pm , for example p_m not = p_w for the proportions are notequal, p_m > p_w for the proportion of men with color blindness is larger, p_m < p_w, for theproportion of men is smaller. )(a) State the null hypothesis:(b) State the alternative hypothesis:(C) The test statistic is(d) Is there sufficient evidence to support the claim that men have a higher rate of red/green colorblindness than women? Use a 10 % significance level.A. YesB. No(e) Construct the 90% confidence interval for the difference between the color blindness rates ofmen and women.< (Pm - Pu) <

A recent survey of 1030 U.S. adults selected at random showed that 627 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.
A. Suppose we want to test whether or not three means are equal. We want to perform this test with a 8% significance level.If we perform an ANOVA test, what is the probability of the test producing accurate results (avoiding a Type I error)? B. Suppose we, instead, run three separate hypothesis tests (t-tests), each with 8% significance level. Mean 1 = Mean 2Mean 1 = Mean 3Mean 2 = Mean 3What is the probability that all three tests would be accurate? C. Why is an ANOVA test more accurate than 3 different tests?
Winning team data were collected for teams in different sports, with the results given in the accompanying table. Use a 0.05 significance level to test the claim that home/visitor wins are independent of the sport. Given that among the four sports included here, baseball is the only sport in which the home team can modify field dimensions to favor its own players, does it appear that baseball teams are effective in using this advantage? Click the icon to view the data table. Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho: Basketball games are more likely to win at home than any other sport. H₁: Basketball games are not more likely to win at home than any other sport. OB. Ho: Basketball games are not more likely to win at home than any other sport.

The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? No(did not lie) Yes(lied) Polygraph test indicated that the subject lied. 14 47 Polygraph test indicated that the subject did not lie. 9 12 Determine the test statistic.
