Which number is not composite? 17,33,39, or 132 number is not composite? 17,33,39, or 132

a) For this case we have , and this value is higher than 0, so then would be on the right tail. And we can find the probability in the tail like this:

b) For this case we have , and this value is higher than 0, so then would be on the right tail. And we can find the probability in the tail like this:

c) For this case we have , and this value is lower than 0, so then would be on the left tail. And we can find the probability in the tail like this:

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

Part a

For this case we have , and this value is higher than 0, so then would be on the right tail. And we can find the probability in the tail like this:

Part b

For this case we have , and this value is higher than 0, so then would be on the right tail. And we can find the probability in the tail like this:

Part c

For this case we have , and this value is lower than 0, so then would be on the left tail. And we can find the probability in the tail like this:

The results are on the figure attached for this case.
