Question

Let x represent the amount of snow (in inches) that fell in Name, Last winter. Constructing and Graphing Discrete Probability Distributions Exercises 19 and 20. (a) construct a probability distribution, and (b) graph the probability distribution using a histogram and describe its shape. Television The number of televisions per household in a small town. Overtime Hours The number of overtime hours worked in one week per employee. Finding Probabilities Use the probability distribution you made in Exercise 19 to find the probability of randomly selecting a household that has (a) one or two televisions, (b) two or more televisions, and (c) between one and three televisions, inclusive. Finding Probabilities Use the probability distribution you made in Exercise 20 to find the probability of randomly selecting an employee whose overtime is (a) two or three hours, (b) three hours or less, and (c) between two and five hours, inclusive. Unusual Events In Exercise 19, would it be unusual for a household to have no televisions? Explain your reasoning. Unusual Events In Exercise 20, would it be unusual for an employee to work two hours of overtime? Explain your reasoning. Determining a Missing Probability In Exercises 25 and 26 determine to missing probability value for the probability distribution.

Explanation / Answer

Question 20 Probability Chart

Probability of working two hours of overtime to an employee is 0.0625 which is higher to 0.05 & it would the case of unusual only if <0.05. We conclude that it would n't be the case of unusual.
