- A sample of individuals of interest is drawn from a population.
For the given case
Individuals of interest:
Students enrolled in accounting class
Population of interest:
Students enrolled in accounting class
Characteristic of interest:
Average GPA of the students enrolled in her class.
a) The population is all students enrolled in the accounting class.
The given statement is true as it contains all the observation of all the individuals of interest.
b) The computed average GPA of all the students enrolled in the class is 3.29
Statistic is a descriptive measure that describes a sample where as a parameter is a measure that describes the population.
Since 3.29 is the average of all the students enrolled in her class that is the average GPA of population.

Answer:
P = 9
Step-by-step explanation:
To find y :
[2x + 4y = 10] (x1)
[x + 9y = 12] (x2)
--------------------------- -
2x + 4y = 10
2x + 18y = 24
-------------------------- -
4y = 10
18y = 24
-------------------------- -
14 y = 14
y = 1
To find x :
x + 9y = 12
x + 9(1) = 12
x = 12 - 9
x = 3
Put the x and y to find P
P = x + 6y
P = 3 + 6(1)
P = 9
