The correct answer is A
Explanation:
Rigid foam board insulation is the one which comprise of the sheets of polyiso, polyurethane or polystyrene foam which is a closed cell as opposite of the open cell.
Closed cell board insulation is strong and possesses the higher R value than the open cell insulation.
Rigid board insulation is the kind of insulation which is used for work on the basement walls, on the flat roofs as a perimeter insulation at the concrete edges of slab.
Correlation is a measure to define the relationship between two variables.
<u><em>Error in each of the given statements is briefly explained as follows:</em></u>
<u><em /></u>
- a). In the first statement, gender refers to a nominal variable and income refers to a continuous variable. It is not possible to compute the correlation between a continuous variable and a nominal variable. Hence, there exists no correlation between the income of American workers and their gender.
- b). It is not possible to have a value of correlation as 1.09 between two variables. It is because the value of correlation ranges between -1 to +1. Thus, the value of correlation i.e. 1.09 is computed wrongly in this statement.
- c). Correlation represents the relationship between two variables; it cannot compute the number of bushels. Therefore, in this statement number of bushels cannot be assigned to correlation.
<u><em>The complete question is:</em></u>
“
Each of the following statements contains an error. Explain what’s wrong in each case.
(a) "There is a high correlation between the gender of American workers and their income."
(b) "We found a high correlation (r = 1.09) between students’ ratings of faculty teaching and ratings made by other faculty members."
(c) "The correlation between planting rate and yield of corn was found to be r = 0.23 bushel."

Answer:
$27,600
Explanation:
The maximum amount that the university should pay must be equal to the variable costs of the personnel department. The department's total costs are $35,500 and the variable costs are $22,000 and the avoidable fixed costs are $5,600, so as long as the university pays up to $27,600 (= $22,000 + $5,600) to the outside vendor, then it will not have increased its total costs.
The fixed non-avoidable costs = $35,500 - $22,000 - $5,600 = $7,900 will remain regardless of what decision is made. If the university pays more than the variable costs and avoidable fixed costs, e.g. $28,000, then total costs would be $36,900 which results in a $400 increase.

Answer: New Market price =$29.55
Explanation:
Using the CAPM,Capital Asset Pricing Model CAPM formule , The expected return on stock is given as
Er = Rf +β( Mr)
which means
Expected return = Risk free rate + beta (market risk premium)
13%= 4% +beta (6%)
beta= 13%-4%/6%=0.13-0.04 /0.06
beta= 1.5
The dividend expected to be paid is given as
Expected dividend, D = Price of security X Expected return
= 50 X 13%
= $6.5
Now, if beta doubles, Expected return becomes
Er = Rf + 2β( Mr)
Er= 4% + 2 x 1.5( 6%)
=4%+ 3.0( 6%)
0.04 + 0.18
Er = 0.22 = 22%
New Market price
Expected dividend, D = Price of security X Expected return
Price = Expected dividend, D/Expected return
= $6.5/0.22
=$29.55
