It is interested in the mean amount of time individuals spend at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was 4 hours with a sample standard deviation of 1.2 hours. Define the random variables X and 
in words.
Answer:
(B)
- X is the amount of time an individual waits at the courthouse to be called for service.
- is the mean wait time for a sample of individuals.
Step-by-step explanation:
The random variable X is the amount of time for which each of the prospective juror waits at the courthouse before being called for service.
is the mean wait time for a the given sample of individuals. In the case given,
Answer:
A&C
Step-by-step explanation:
As, you said, the first answer is C. Now, we are given seven, and when we are adding a negative number, we move in the direction of left, and since we are moving by 7, we would be moving 7 to the left. Therefore, the other answer is A.
first one it is the absolute value of -3 and the other one is -3 itself absolute value of -3 mean 3
Answer:
Step-by-step explanation:

Answer:
Therefore the Final Solution is x = 2 and y = 7
i.e (2 ,7)
Step-by-step explanation:
Given:
...............Equation ( 1 )
...............Equation ( 2 )
..............Equation ( 3 )
To Find:
x = ?
y = ?
Solution:
Substituting Equation ( 3 ) in Equation ( 1) we get
Now Substituting x = 2 in Equation ( 3 ) we get
Therefore the Final Solution is x = 2 and y = 7
i.e (2 ,7)
