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.

Step-by-step explanation:
Answer:
1. 3 days.
Step-by-step explanation:
We have been given that the hurricane George is 1,728 kilometers southeast of Puerto Rico and moving northwest at 24 kilometers per hour.
First of all we will find the number of hours it will take for George to reach Puerto Rico. We can find number of hours taken by hurricane George to reach Puerto Rico by dividing 1728 by 24.
We can see that George will reach Puerto Rico in 72 hours. Let us convert hours to days by dividing 72 by 24 (number of hours in a day).
Therefore, the hurricane George will reach to Puerto Rico in 3 days, if the hurricane stays on its present course. Our first option is the correct choice.
Suppose the length is 7x, the width is then 3x
7x*3x=525
21x²=525
x²=25
x=5
so the length is 7*5=35, and the width is 3*5=15
