Approximately 70% of statistics students do their homework in time for it to be collected and graded. In a statistics class of 50 students, what is the probability that at least 40 will do their homework on time?

Problem 1:

This is a binomial problem because there is only a success or a __________, there are a definite number of trials, and the probability of a success is 0.70 for each trial.

Problem 2:

If we are interested in the number of students who do their homework, then how do we define X?

Problem 3:

What values does X take on?

Problem 4:

What is a "failure", in words?

The probability of a success is p = 0.70. The number of trial is n = 50.

Problem 5:

If p + q = 1, then what is q?

Problem 6:

The words "at least" translate as what kind of inequality?

The probability question is P (X 40).
