A researcher determines that the probability of missing class among students at a local school is p = .16.Assuming that the school has 300 students enrolled,how many students can we expect to miss class on a given day? Hint: This is a binomial probability distribution.
A) 252 students
B) 48 students
C) 16 students
D) There is not enough information to answer this question.

Since we know that this is a binomial probability distribution with p = 0.16, q = 1-p = 0.84, and the sample size n = 300, we can use the formula for expected value in a binomial distribution, which is E(x) = np.

Therefore, E(x) = 300 x 0.16 = 48.

Thus, we can expect 48 students to miss class on a given day.
