Step-by-step explanation:
Previous concepts
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".
Let X the random variable who represent the exam scores for the population, and for this case we know the distribution for X is given by:
Where
and
And let
represent the sample mean, the distribution for the sample mean is given by:
What is the probability that a randomly selected score will be between 69 and 77?
For this case we can use the z score formula given by:
![z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
And that correspond with the 35.75% of the data.
