Miami Beach Medical Clinic (MBMC) has about 17.5 patients arriving per hour on average.  MBMC serves about 20 patients per hour on average. Also, MBMC does NOT follow the traditional M/M/1 model. A patient arriving at this facility is expected to have one of the following wait times of (0 or 1 or 4 or 6 or 8 minutes) in the queue before being served. The probabilities associated with these wait times in the queue are 0.3, 0.2, 0.3, 0.1, and 0.1 respectively. The patient’s average wait time in queue is expected to be: a. 2.3 minutes b. 7.2 minutes c. 5.6 minutes d. 3.9 minutes e. 2.8 minutes

It is known that roughly 2/3 of all human beings have a dominant right foot or eye. Is there also right-sided dominance in kissing behavior? An article reported that in a random sample of 136 kissing couples, both people in 86 of the couples tended to lean more to the right than to the left. (Use α = 0.05.) (a) If 2/3 of all kissing couples exhibit this right-leaning behavior, what is the probability that the number in a sample of 136 who do so differs from the expected value by at least as much as what was actually observed? (Round your answer to three decimal places.)   Calculate the test statistic and determine the P-value.

XYZ Corp has filed 100,000 purchase orders during its existence.  1100 of those purchase orders have had errors.  Using empirical probability, the probability of the next purchase order that XYZ processes having an error is what.

zample 3: Alexis is selling girl scout cookies. She has kept track of the number of boxes of cookies at her customers have purchased over the last 2 years. She wants to use this data to help edict how many boxes of cookies a new customer might purchase. The table below summarizes exis' data, with the number of boxes that a customer might purchase along with the rresponding probability that they will purchase that number of boxes based on her previous les. Use this information to answer the following questions. Outcomes: 2 3 4 5 6 7 8 X = x Probability: P(X = x¡) 0.21 0.16 0.32 0.11 0.08 0.05 0.04 0.02 0.01 a) Construct a probability histogram of the data in the table above and comment on the shape. ) What is the probability that a randomly selected customer will purchase 3 boxes of cookies?
