Jason's data distribution is symmetrical and shows no outliers; Shane's data distribution is uniform and shows no outliers also. Therefore, the correct observation about the data sets that is correct is:<em> Option B.</em>
<h3>Symmetrical and Uniform Data Distribution on a Dot Plot</h3><h3>What are Outliers?</h3>
Outliers are values that are far from the middle and are entirely different from the rest of the data.
The dot plots for sales made by Jason and Shane are shown in the image attached below.
Jason's data distribution is symmetrical and shows no outliers; Shane's data distribution is uniform and shows no outliers also. Therefore, the correct observation about the data sets that is correct is:<em> Option B.</em>

Answer: Option 'c' is correct.
Step-by-step explanation:
Let the number of dimes be 'x'.
Let the number of nickels be ''.
Let the number of pennies be
Let the number of quarters be '3x-34'.
As we know that
1 quarter = $0.25
1 dime = $0.10
1 nickel = $0.05
1 penny = $0.01
According to question, we get that
So, the number of pennies is given by
Hence, Option 'c' is correct.
Answer: Mean = 20 and standard deviation = 4
Step-by-step explanation:
Let x represents the success of getting the correct answer.
Here, the total number of trials(n) = 100
The probability of getting the correct answer, p = 1/5
Thus, the mean of the number of correct answer,
Now, the standard deviation,
Thus, First option is correct.
