Answer:
a)
And using the normal distribution table or excel we got:
b)
And we can use the normal standard table or excel in order to find the probability and we got:
Step-by-step explanation:
For this case we know that the random variable of interest is normally distributed with the following parameters:
Part a
We want to find this probability:
And we can use the z score formula given by:
Replacing we got:
And using the normal distribution table or excel we got:
Part b
We select a random sample of size n = 16 and we try to find this probability:
And we can use the z score formula given by:
And replacing we got:
And we can use the normal standard table or excel in order to find the probability and we got:
