Answer:
And we can find this probability with the normal standard table or excel and we got:
And for this case is not neccesary applt the finite population correction factor since the distribution for the random variable is assumed known and normal
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 length of time 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 with the normal standard table or excel and we got:
And for this case is not neccesary applt the finite population correction factor since the distribution for the random variable is assumed known and normal
The mode would be 1. Mode means the number that is shown the most
