Answer:
The standard deviation of the age distribution is 6.2899 years.
Step-by-step explanation:
The formula to compute the standard deviation is:
The data provided is:
X = {19, 19, 21, 25, 25, 28, 29, 30, 31, 32, 40}
Compute the mean of the data as follows:
Compute the standard deviation as follows:
Thus, the standard deviation of the age distribution is 6.2899 years.
Answer:
(728, 748)
Step-by-step explanation:
You need the Z value which for 95% confidence interval is 1.96. The mean is $738 and the standard deviation of $41.
Therefore we can calculated the confidence interval
The interval is (728,748)
Answer:
The ordered pair that corresponds to point P is: (4, 2)
Step-by-step explanation:
It is clear from the graph that the point P is located at the location (4, 2).
In other words,
at x = 4, y = 2
It means:
The x-coordinate of the point P is: x = 4
The y-coordinate of the point P is: y = 2
Thus, the location of the point P → P(x, y) = P(4, 2)
Please check the attached graph.
Therefore, we conclude that:
The ordered pair that corresponds to point P is: (4, 2)
