Answer:
And we can find this probability using the complement rule and with excel or the normal standard table:
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 weights of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and with excel or the normal standard table:
Well If your trying to turn it into a decimal the answer would be .25 but if you want it as a fraction the answer is 100 over 25. Hope I helped!

Answer:
8%
Step-by-step explanation:
To find the percent, divide 16 by 200, then multiply it by 100.
(16 / 200) x 100
0.08 x 100
= 8
So, 16 is 8% of 200
