Consider the following joint probability table. B1 B2 B3 B4 A 0....10 Ac 0....17 a. What is the probability that A occurs? (Round your answer to 2 decimal places.) Probability: b. What is the probability that B2 occurs? (Round your answer to 2 decimal places.) Probability: c. What is the probability that Ac and B4 occur? (Round your answer to 2 decimal places.) Probability: d. What is the probability that A or B3 occurs? (Round your answer to 2 decimal places.) Probability: e. Given that B2 has occurred, what is the probability that A occurs? (Round your intermediate calculations and final answers to 4 decimal places.) Probability: f. Given that A has occurred, what is the probability that B4 occurs? (Round your intermediate calculations and final answers to 4 decimal places.) Probability: 1- Listed below is a list of how long it takes for bands on stage to complete their first song (in seconds). What is the standard deviation in the time it takes for bands on stage to complete their first song (in seconds)? Round your answer to two decimal places. 2-Listed below is a list of how long it takes for bands on stage to complete their first song (in seconds). Suppose a new band joins this group and performs for 4 minutes. Would this new band be considered unusual? Please explain. 3-Seventeen people are randomly chosen from people in the U.S. and asked "Do you have brown eyes?" Does this procedure result in a binomial distribution? Explain carefully. 4- In the United States, 40% of the population have brown eyes. If 17 people are randomly selected, find the probability that exactly 4 of them will have brown eyes. Your answer should be rounded to four decimal places. 5- Use Table A-2 to find P( 0.63 0.25 c. p = 0.25 d. p 0.25 c. p = 0.25 d. p ≠0.- A survey of 61,647 people included questions about office relationships. Of the respondents, 26% reported that their bosses scream at employees. Suppose you want to test the claim that more than 1/4 of people say their bosses scream at employees. What is the alternative hypothesis? a. p 0.25 c. p = 0.25 d. p ≠0.- A survey of 61,647 people included questions about office relationships. Of the respondents, 26% reported that their bosses scream at employees. Suppose you want to test the claim that more than 1/4 of people say their bosses scream at employees. What kind of hypothesis test would you use? a. left-tailed b. two-tailed c. no tailed d. right-tailed 13- A survey of 61,647 people included questions about office relationships. Of the respondents, 26% reported that their bosses scream at employees. Suppose you want to test the claim that more than 1/4 of people say their bosses scream at employees. Calculate the test statistic and round it to two decimal places. 14- A survey of 61,647 people included questions about office relationships. Of the respondents, 26% reported that their bosses scream at employees. Suppose you want to test the claim that more than 1/4 of people say their bosses scream at employees. If you use a 0.05 significance level, what is the critical value? a. -1.96 b. 1.645 c. 1.96 d. -1.- A survey of 61,647 people included questions about office relationships. Of the respondents, 26% reported that their bosses scream at employees. Suppose you want to test the claim that more than 1/4 of people say their bosses scream at employees. If you use a 0.05 significance level, which of the following is the conclusion of your hypothesis test? a. fail to reject the alternative hypothesis b. fail to reject the null hypothesis c. reject the null hypothesis d. accept the null hypothesis 16- A survey of 61,647 people included questions about office relationships. Of the respondents, 26% reported that their bosses scream at employees. Suppose you want to test the claim that more than 1/4 of people say their bosses scream at employees. If you use a 0.05 significance level, which of the following is the conclusion of your hypothesis test? a. There is not sufficient evidence to warrant rejection of the claim that more than 1/4 of people say that bosses scream at employees. b. There is not sufficient sample evidence to support the claim that more than 1/4 of people say that bosses scream at employees. c. There is sufficient evidence to warrant rejection of the claim that more than 1/4 of people say that bosses scream at employees. d. The sample data support the claim that more than 1/4 of people say that bosses scream at employees.
