What is the probability that a randomly chosen patient has a pain level of 4 or higher? points: 5 For problems 1 and 2: Patients receiving artificial knees often experience pain after surgery. The pain is measured on a subjective scale with possible values of 1 (low) to 5 (high). Let X be the pain score for a randomly selected patient. The following table gives part of the probability distribution for X. X 3 5 P(X) 0.1 0.2 0.3 0.3 0.1 O 0.1 O 0.3 O 0.4 O 0.6 2. What is the expected value of pain? points: 5 For problems 1 and 2: Patients receiving artificial knees often experience pain after surgery. The pain is measured on a subjective scale with possible values of 1 (low) to 5 (high). Let X be the pain score for a randomly selected patient. The following table gives part of the probability distribution for X. X 3 5 P(X) 0.1 0.2 0.3 0.3 0.1 O 3.1 O 2.5 O 1.0 O 1.5 O 3.5 3.

The shelf life of a particular dairy product is normally distributed with a mean of 12 days and a standard deviation of 3 days. About what percent of the products last between 12 and 15 days? points: 5 O 50% O 68% O 34% O 7.6% 6. Find the value of k given the probability dist. below. points: 5 A random variable X has a probability distribution as follows: X 0 1 2 3 P(X) 2k 3k 13k 2k O 1.0 OO O 0.15 O 0.10 O 0.05 7. What does the standard deviation represent? points: 5 How many different variations are in the data set. How spread out each data value is from the mean. O How the population varies compared to the sample. O The range, but with a bunch of other stuff going on
