Answer:
-54
Step-by-step explanation:
-6 * 10 + 6
-60 + 6
= -54
100 = 50 *2
= 25 * 2 * 2
= 5 * 5 * 2 * 2
=
5 * 2 = 10
~~~~~~~~~~
36 = 6 * 6 = 3 * 3 * 2 * 2 = 3^2 ^ 2^2
3*2 = 6

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".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the following conditions
Where and
And for this case we select a sample size of n= 15. and we want to know the distribution for the sample mean . We can assume that the distribution for
is approximately normal and given by:
Asuming that the distribution for X is also approximately normal. So then the parameters are:
