Answer:
a) True
b) Parameter
Step-by-step explanation:
We are given the following in the question:
An accounting professor wants to know the average GPA of the students enrolled in her class.
Population:
- It is defined as the collection of all variables of interest.
- 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.
Thus, 3.29 is a parameter.
Answer:
12m
Step-by-step explanation:
You can break this shape down into a square and a trapezoid. Frist you can find the area of the square by multiplying 2 by 5 to get 10. Then you would find the area of a trapezoid by doing Area = 1/2height(base1+base2). We can find the height by subtracting 5 from 9. (We do this because we know the side of the square is 5m) Therefore the height would be 4m. We know the bases are 2 and 4. From there you can plug those numbers in to the formula. Area=1/2 * 4 (2 + 4)
Area= 1/2 * 4 (6)
Area = 2(6)
Area = 12m
R - Right Handed
L - Left Handed
R = 9L ( the number of right handed kids is equal to having 9*number of left handed kids)
9L + L = 30 ( since total number of people in class is 30)
10L = 30
( Divide by 10 both sides )
L = 3
so... There are 3 Left Handed kids and 27 Right Handed kids ( since R = 9L , R = 9(3) = 27)
Hope this helped!
