CAN YOU PLEASE ANSWER THE WHOLE THING?
Georgia residents spent an average of $470 on the lottery in 2010, or 1% of their personal income (www.msn.com, May 23, 2012). Suppose the amount spent on the lottery follows a normal distribution with a standard deviation of $50. If five Georgians are randomly selected, what is the probability that the average amount spent on the lottery was more than $500? (Round your answer to three decimal places.)
Business Weekly conducted a survey of graduates from 30 top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is $133,000. Assume the standard deviation is $45,000. Suppose you take a simple random sample of 22 graduates. Round all answers to four decimal places if necessary. For a single randomly selected graduate, find the probability that her salary is between $136,209 and $142,906. For a simple random sample of 22 graduates, find the probability that the average salary is between $136,209 and $142,906. For part 2), is the assumption of normal necessary? No Yes
TV sets: According to the Nielsen Company, the mean number of TV sets in a U.S. household in 2013 was 2.24. Assume the standard deviation is 1.2. A sample of 80 households is drawn. Part 1 of 5 What is the probability that the sample mean number of TV sets is greater than 2? Round the answer to four decimal places. The probability that the sample mean number of TV sets is greater than 2 is Part 2 of 5 What is the probability that the sample mean number of TV sets is between 2.5 and 3? Round the answer to four decimal places. The probability that the sample mean number of TV sets is between 2.5 and 3 is .
Business Weekly conducted a survey of graduates from several top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is $124,000. Assume the standard deviation is $42,000. Suppose you take a simple random sample of 17 graduates. Round all answers to four decimal places if necessary What is the standard deviation of ¯¯¯XX¯? For a single randomly selected graduate, find the probability that her salary is between $111,920 and $125,213. For a simple random sample of 17 graduates, find the probability that the average salary is between $111,920 and $125,213.
Electricity bills: According to a government energy agency, the mean monthly household electricity bill in the United States in 2011 was $108.87 . Assume the amounts are normally distributed with standard deviation $18.00 . Use the TI-84 Plus calculator to answer the following. (a) What proportion of bills are greater than $134 ? (b) What proportion of bills are between $83 and $145 ? (c) What is the probability that a randomly selected household had a monthly bill less than $118 ? Round the answers to at least four decimal places. Part 1 of 3 The proportion of bills that are greater than $134 is . Part 2 of 3 The proportion of bills that are between $83 and $145 is . Part 3 of 3 The probability that a randomly selected household had a monthly bill less than $118 is .
Cody took his first physics exam and scored an 80. The population mean for this exam is 70, and the standard deviation is 5. What is the probability of selecting a person with a score greater than Cody’s?
Business weekly conducted a survey of graduates for 30 top MBA programs. On the basis of the survey assume the means annual salary 10 years after graduation is $162,000. Assume the standard deviation is $40,000. Suppose you take a simply random sample of 39 graduates. For a single randomly selected graduate, find the probability that her salary is between $156,692.00 and $161,395.00. For a simple random sample of 39 graduates, find the probability that the average salary is between $156,692.00 and $161,395.00. Is the assumption of normal necessary? Yes, or No.
A stock can earn a return of 10%, 15%, -5%, or 0%, each with a known probability of 25%. What is the standard deviation of this stock's return? Select one: O a. .025 b. .079 c..05 d. .00625 e..0913
Business Weekly conducted a survey of graduates from 30 top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is $136,000. Assume the standard deviation is $39,000. Suppose you take a simple random sample of 9 graduates. Round all answers to four decimal places if necessary.
The median annual cost of auto insurance is $ 939 (According to DACO). Suppose the standard deviation is o = $ 241. What is the probability that in a simple random sample of auto insurance policies the sample mean differs more than $ 70.42 from the population mean if the sample size is 45? You must calculate the probability that the difference between the average cost in the sample and the average annual cost do not differ by $ 70.42. Find the probability that P (\ µ - š | 0) = P (-70.42 H-iS 70.42) Select one: a. The probability is 99% that the auto policy will not differ by $ 70.42 from the average annual cost. b. The probability is 50% that the auto policy will not differ by $ 70.42 from the average annual cost. c. The probability is 80% that the auto policy will not differ by $ 70.42 from the average annual cost. d. The probability is 70% that the auto policy will not differ by $ 70.42 from the average annual cost. e. The probability is 95% that the auto policy will not differ by $…
Business Weekly conducted a survey of graduates from 30 top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is $190,000. Assume the standard deviation is $34,000. Suppose you take a simple random sample of 15 graduates. Round all answers to four decimal places if necessary. For a simple random sample of 15 graduates, find the probability that the average salary is between $180,932 and $187,421. For part d), is the assumption of normal necessary? NoYes
