Skee Ball Refer to Exercise 4. Make a histogram of the probability distribution. Describe its shape

Short Answer

Expert verified

The scores range from ten to fifty.

The most common score is a 10 that is skewed to the right.

The scores range from ten to fifty.

Step by step solution

01

Step 1. Given information.

Score1020304050
Probability0.320.270.190.150.07
02

Step 2. Create a probability distribution histogram. Describe its form.

Histogram of Probability

Each bar's width must be the same, and the bars must be centered on the amount of money collected, with the height equal to the probability.

Because the highest bar in the histogram is to the left, and there is a tail of smaller bars to its right, the distribution is skewed to the right.

Because the highest bar in the histogram is centered at 10, the most common score is 10.

As a result:

The scores range from ten to fifty.

The most common score is a 10 that is skewed to the right.

The scores range from ten to fifty.

Skee BallAna is a dedicated Skee Ball player (see photo in Exercise 4) who always rolls for the 50-point slot. The probability distribution of Ana鈥檚 score Xon a randomly selected roll of the ball is shown here. From Exercise 8, 渭X=23.8.

(a) Find the median of X.

(b) Compare the mean and median. Explain why this relationship makes sense based on the probability distribution.

Auto emissions The amount of nitrogen oxides {NOX}) present in the exhaust of a particular type of car varies from car to car according to a Normal distribution with mean 1.4grams per mile (g/mi) and standard deviation 0.3g/mi. Two randomly selected cars of this type are tested. One has 1.1g/miof NOX; the other has 1.9g/mi. The test station attendant finds this difference in emissions between two similar cars surprising. if the NOX levels for two randomly chosen cars of this type are independent, find the probability that the difference is at least as large as the value the attendant observed.follow the four-step process.

Red light! Pedro drives the same route to work on Monday through Friday. His route includes one traffic light. According to the local traffic department, there is a 55%chance

that the light will be red on a randomly selected work day. Suppose we choose 10 of Pedro's work days at random and let Y= the number of times that the light is red. Make a graph of the probability distribution of Y . Describe its shape.
