Answer:
The probability that the mean of the sample is greater than $325,000
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given the mean of the Population( )= $290,000
Standard deviation of the Population = $145,000
Given the size of the sample 'n' = 100
Given 'X⁻' be a random variable in Normal distribution
Let X⁻ = 325,000
<u><em>Step(ii):</em></u>-
The probability that the mean of the sample is greater than $325,000
= 0.5 - A(2.413)
= 0.5 - 0.4920
= 0.008
<u><em>Final answer:-</em></u>
The probability that the mean of the sample is greater than $325,000

[ Explanation ]
4(y + 6) - 2(y - 2)
[Expand] 4(y + 6): 4y + 24
4y + 24 - 2(y - 2)
[Expand] -2(y - 2): -2y + 4
4y + 24 - 2y + 4
[Simplify] 4y + 24 - 2y + 4: 2y + 28
= 2y + 28
