Answer:
i'm pretty sure it's d hope this helps
Step-by-step explanation:
1,000,000 because since it is 100,000 the closest number is 1,000,000
Answer:
And using the normal standard table or excel we find the probability:

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 avergae number of weeks an individual is unemployed of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then, the distribution for the sample mean
is given by:
We select a sample of n =50 people. And we want to find the following probability
And using the normal standard table or excel we find the probability:

Let blueberry = b and poppyseed = p
b + p = 64
b = p + 20
p + 20 + p = 64
2p + 20 = 64
2p = 44
p = 22
b = 22 + 20
b = 42
