II Suppose for our purposes that I wanted information about all students currently taking statistics at GPC. To do this grouped the students by the section they were in then I randomly chose two of the sections. Using this scenario, please answer each of the following: 1. Complete the following chart using the data set provided: Frequency Major Accounting Biology Business Administration Education Nursing Health Science Social Work/Sociology Other Using the chart above, answer the following: a. What is the probability a student is majoring in Business Administration? b. What is the probability that a student is not majoring in Nursing/Health Science? C. What is the probability that a student is majoring in Social Work/Sociology or Education? 2. Complete the chart below with the frequencies using the data set provided: Marital Status Fan of “Scandal Not a fan of Totals “Scandal” Single Married Divorced Totals Using the chart above, answer the following: a. What is the probability a student is married and is a fan of “Scandal? b. What is the probability a student is single or is not a fan of “Scandal”? c. Given that a student is Single, what is the probability that they are a fan of “Scandal”? d. Given that a student is a fan of “Scandal”, what is the probability that they are Married? 3. Complete the following: Suppose the probability that a student is left handed is known to be 0.27. Given a class of 34 students selected at random, what is the probability that: a. Exactly 6 students are left handed. b. More than 10 students are left handed. c. At most 4 students are left handed.
4. Complete the following probability chart using the data chart provided: Number of Siblings x P(x) 0 10 Using the chart above, answer each of the following: a. Find the mean of the probability distribution. b. Find the standard deviation of the probability distribution. c. What is the probability that a student has at least 3 siblings? d. What is the probability that a student has at most 5 siblings? 5. Using the data set provided, find the expected number of hours that a student studied per week for our sample. 6. Suppose I was given that the mean number of hours studied by statistic students in general is normally distributed with mean 11.3 and standard deviation 2.3. a. What is P(x<= 8)? b. What is P(2 <= x <= 5)? c. What is P(x >= 10)? 7. Suppose that I know that in general the mean number of hours of sleep for statistic students is 5.2 with a standard deviation of 2.7. Suppose I have a sample of n = 34. a. Describe the distribution of s-bars. b. Determine P(x-bar >= 7). c. Determine P(x-bar <= 4).
