The accompanying table shows results of challenged referee calls in a major tennis tournament. Use a 0.05 significance level to test the claim that the gender of the tennis player is independent of whether a call is overtu E Click the icon to view the table. Determine the null and altemative hypotheses. O A. Ho: Male tennis players are not more successful in overturning calls than female players. H,: Male tennis players are more successful in overturning calls than female players. O B. Ho: Male tennis players are more successful in overturning calls than female players. H,: Male tennis players are not more successful in overturning calls than female players. O C. Ho: The gender of the tennis player is not independent of whether a call is overturned. H: The gender of the tennis player is independent of whether a call is overturned. D. Ho: The gender of the tennis player is independent of whether a call is overturned. H,: The gender of the tennis player is not independent of whether a call is overtuned. Determine the test statistic. x2 = 27.973 (Round to three decimal places as needed.) Determine the P-value of the test statistic. P-value = (Round to four decimal places as needed.)

Mitt Romney was a presidential candidate in the Novem-ber 2012 U.S. presidential elections and he is a Mormon. The Public Religion Research Institute, during its 2011American Values Survey, asked 1019 random Americansif they would be comfortable with a Mormon serving asPresident. Fifty three percent reported that they wouldbe somewhat or very comfortable with this. Which ofthe following hypotheses should we test to determinewhether the majority of Americans would be somewhator very comfortable with a Mormon serving as president?A) H0 : p = 0.50 HA: p ≠ 0.50B) H0 : p = 0.50 HA: p 6 0.50C) H0 : p = 0.50 HA: p 7 0.50D) H0 : p = 0.53 HA: p 7 0.53E) H0 : pn = 0.53 HA: pn ≠ 0.53(Source: http://publicreligion.org/research/2011/11/2011-american-values-survey/)

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 285 people over the age of 55, 76 dream in black and white, and among 287 people under the age of 25, 10 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Test the claim using a hypothesis test. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 = P2 H: P1> P2 O B. Ho: P1 = P2 OC.

Researchers collected data on the numbers of hospital admissions resulting from motor vehicle​ crashes, and results are given below for Fridays on the 6th of a month and Fridays on the following 13th of the same month. Use a 0.05 significance level to test the claim that when the 13th day of a month falls on a​ Friday, the numbers of hospital admissions from motor vehicle crashes are not affected.

A police department released the numbers of calls for the different days of the week during the month of October, as shown in the table to the right. Use a 0.01 significance level to test the claim that the different days of the week have the same frequencies of police calls. What is the fundamenta error with this analysis? Day Frequency Sun 154 Mon 205 Tues 230 Thurs 177 Fri 210 Sat 230 Wed 241 Determine the null and alternative hypotheses Calculate the test statistic. r=ORound to three decimal places as needed.) Calculate the P-value. Pvalue =O (Round to four decimal places as needed.)
