Step-by-step explanation:
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
The population proportion have the following distribution
And we can solve the problem using the z score on this case given by:
We are interested on this probability:
And we can use the z score formula, and we got this:
And we can find this probability like this:
Answer:
The point is P(2,7)
Step-by-step explanation:
We are given the following information in the question:
A point is located in the quadrant 1 in the following manner:
It has x-value that is 2 units from the origin.
It has a y-value 7 units from the origin.
Thus, the point is (2,7)
The attached image shows the marked point (2,7).
