The experimental probability in this problem is given by the total amount of silver coins Clarisse pulled over the total amount of coins Clarisse pulled.
She pulled 48 silver coins out of the 60 she pulled in total. Set up a fraction:
This fraction can be simplified by dividing both the numerator and denominator by 12:
The experimental probability of pulling another silver token is
4/5.
For deck,
Length = 2x + 1
Width = 5x + 2
For pool,
Length = 2x
Area of deck including pool = (2x + 1)(5x + 2) = 10x^2 + 4x + 5x + 2 = 10x^2 + 9x + 2
Area of pool = 2x * 2x = 4x^2
Area of only the deck = 10x^2 + 9x + 2 - 4x^2
= 6x^2 + 9x + 2

Answer:
The group that has greater value of relative dispersion is the smokers group, as the coefficient of variationof their data is bigger than the coefficient of variation of the non-smokers group data.
CV smokers: 0.387
CV non-smokers: 0.234
Step-by-step explanation:
We will calculate the relative dispersion of each data set with its coefficient of variation (ratio of the standard deviation to the arithmetic mean).
Then, first we calculate the mean and standard deviation for the smokers data:
Mean: 43.7
Standard deviation: 286.5
The mean and standard deviation for the non-smokers is:
Mean: 30.3
Standard deviation: 50.9
Now, we can calculate the coefficient of variation:
CV smokers:
CV non-smokers:
