Explanation:
The z score is a used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

a) Given that n = 100, μ = 2000, σ = 18
For x < 1995 millimeters:

From the normal distribution table, P(x < 1995) = P(z < -2.78) = 0.0027
b) P(z > z*) = 10% = 0.1
P(z < z*) = 1 - 0.1 = 0.9
z* = 1.28

From the normal distribution table, P(z < z

Answer:
8.82%
Explanation:
The computation of the portfolio return is shown below:
Portfolio return = Respective returns ×Respective weights
= (10.8 × 0.45) + (12.2 × 0.35) + (-1.56 × 0.20)
= 8.82%
Hence, the portfolio return is 8.82%
We simply applied the above formula so that the portfolio return could come

Answer:
If American produces the new compound, profit will increase by $88,000
Explanation:
increase in selling price = selling price of new variant of chemical - selling price of chemical compound
= $83 - $52
= $31
Net increase in profit = total increase in selling price - additional processing cost
= $31*8000 - $160000
= $248000 - $160000
= $88,000
Therefore, If American produces the new compound, profit will increase by $88,000.
net increase in profit =
