Answer:
1. $29.4 million
2. 145.24
3. 145.24
4. 12.05
5. D. No, because the sample is not representative of the whole population.
Step-by-step explanation:
1. The computation of range of the sample data is shown below:-
Range of the sample data = Maximum value - Minimum value
= 42 - 12.6
= $29.4 million
2. For the computation of variance of the sample data first, we need to find out the mean which is shown below:-
Mean =
= 24.83
The Variance of the sample data
=
=
= 145.24
3. The computation of the standard deviation of the sample data is shown below:-
The Standard deviation of the sample
=
= $12.05155592
or
$12.05
4. No, as the sample does not represent the whole population.
Answer:
x>24.75
Step-by-step explanation:
The given equation is :
Add 9 to both sides of the inequality.
Multiply 5 to both sides of the inequality.
Dividing both sides by(-2)
or
Hence, the value of x is greater than 24.75.
