2. Approximately 70% of statistics students do their homework in time for it to be collected and graded. Each student does homework independently. In a statistics class of 50 students, what is the probability that at least 40 will do their homework on time? Students are selected randomly. a. Explain why this is a binomial probability distribution. (2 pts.) (Hint: Check the properties of a binomial distribution) e. Define the random variable X. (2 pts.) (Hint: Describe in words what X stands for) b. What values X will take on? (2 pts.) c. Write down the values for n and p. (2 pts.) n p= d. Write down the probability statement and calculate the probability that at least 40 students will do their homework on time. (2 + 2 = 4 pts.)
