6. (5 Marks) A group of four undergraduate and five graduate students are available to fill certain student government posts. If four students are to be randomly selected from this group, a) Find the probability that exactly two undergraduates will be among the four chosen. (2 points) b) What is the probability that at least two graduate students be chosen? (3 points)
Many students accumulate debt by the time they graduate from college. Shown in the following table is the percentage of graduates with debt and the average amount of debt for these graduates at four universities and four liberal arts colleges.

Currently 25% of students entering colleges or universities comparable to UNC Charlotte graduate within four years. Find the probability that in a random sample of 300 students who began college this semester at least 25%will graduate with four years.
Question 1 (Normal Approximation). Suppose that 25% of Rackham graduate students are Graduate Student Instructor (GSI). Now, select a random sample of 50 Rackham graduate students. Let X be the number of Rackham graduate students in the random sample who are GSI. (a) What is the distribution of X? (b) Approximate X using a normal random variable Y and provide the mean and variance of Y. Explain all the required conditions for this approximation (c) What is the approximate probability...
Will rate!! Suppose 81% of all students taking a beginning programning course fail to get their first program to run on first submission. Consider a group of S such students,where each student's success is independent from the other and the chance each student fails on their first try is consistent. (Round answers to three decimal places.) (a) If X is the number of students whose program fails on the first run, then X comes from a binomial distribution with: n-...
Suppose that there are 100 MBA students in the first-year class. Of these students, 20 of them have two years of work experience, 30 have three years of work experience, 15 have four years of work experience, and 35 have five or more years of work experience. Suppose that a first-year MBA student is selected at random. a) What is the probability that this student has at least 4 years of work experience? b) Suppose that you are told that...

5. In a math class consisting of 21 students, suppose that 10 of the enrolled students are rated as “very proficient" in math, according to a standardized test. (a) (4 points) Suppose 4 students in the class are randomly selected to form a group and work on a project. What is the probability that all of the students in the group are rated as very proficient in math? (b) (4 points) If 4 students in the class are randomly selected,...
suppose that 50% of all college students smoke cigarettes. a sample of 12 is selected randomly. what is the probability that between 6 and 10 (both inclusive) students smoke? round your answer to four decimal places.
A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentive and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 90.4% for the medical students admitted through special programs. Be sure to enter at least 4 digits of accuracy for this problem! - If 9 of the students from the special programs are randomly selected, find the...
