Question

Determine whether the distribution is a discrete probability distribution

X. 1 2 3 4 50
P(x) 0.28 0.45 0.11 0.08 0.08




Is the distribution a discrete probability distribution?

O A. Yes, because the sum of the probabilities is equal to 1 and each probability is between 0 and 1, inclusive.

OB. No, because each probability is not between 0 and 1, inclusive.

O c. Yes, because the sum of the probabilities is equal to 1.

OD. No, because the sum of the probabilities is not equal to 1.

Answer 1

A child psychologist is interested in the number of times a newborn baby’s crying wakes its mother after midnight. For a random sample of 50 mothers, the following information was obtained. Let X = the number of times per week a newborn baby’s crying wakes its mother after midnight. For this example, x = 0, 1, 2, 3, 4, 5.

P(x) = probability that X takes on a value x.

x P(x)0 P(x = 0) = 250

1 P(x = 1) = 1150

2 P(x = 2) = 2350

3 P(x = 3) = 950

4 P(x = 4) = 450

5 P(x = 5) = 150
