Answer:
And we can find this probability using the normal standard distribution and we got:
Step-by-step explanation:
For this case we have the foolowing parameters given:
represent the mean
represent the standard deviation
the sample size selected
And for this case since the sample size is large enough (n>30) we can apply the central limit theorem and the distribution for the sample mean would be given by:
And we want to find this probability:
We can use the z score formula given by:
And we can find this probability using the normal standard distribution and we got:
