Answer:

The probability more than 72% of the cardholders are carrying a balance is 0.2946

Explanation:

Test statistic (z) = (p' - p) ÷ sqrt[p(1-p) ÷ n]

p' is the sample proportion = 0.72

p is the population proportion = 0.74

n is the number of cardholders sampled = 140

z = (0.72 - 0.74) ÷ sqrt[0.74(1-0.74) ÷ 140] = -0.02 ÷ 0.037 = -0.54

The cumulative area of the test statistic is the probability that less than 72% of the cardholders are carrying a balance. The probability is 0.7054.

Probability (more than 72% of the cardholders are carrying a balance) = 1 - 0.7054 = 0.2946

You invested in a $5,000 bond in 2012 with a coupon rate of 6%. What will be its value in 2018 if the required rate of return is
ELEN [110]

Answer:

$4540.19

Explanation:

Step 1: Get the formula for the value of the bond  in 2018

Formula= P * (1+r)n

P= Investment = $5000

r= Coupon rate=6%

n= Period or number of years = 6 years

Step 2: Calculate the value of the bond in 2018

Value of the bond in 2018= 5000 * (1+ 0.06)6

= 7092.60

Step 3: Calculate the Present value of the bond

Formula= (P x Present Value Factor) + (Interest x The present value interest factor of an annuity (PVIFA))

(P x Present Value Factor) = (5000 x 1\(1+r)^n)

where r= rate of return= 8%

n= years = 6

(Interest x The present value interest factor of an annuity (PVIFA) =

Interest = (Coupon rate x Investment)

PVIFA= 1\(1+r)^n}

where r= rate of return= 8%

n= years = 6

= (5000 x  0.6307) + (300 x 4.6223 )

=4540.19

Lock Division of Morgantown Corp. sells 80,000 units of part Z-25 to the outside market. Part Z-25 sells for $40, has a variable
Kisachek [45]

Answer:

The effect on Morgantown's overall profit is $140,000 decrease in Morgantown's profits

Explanation:

In order to calculate the effect on Morgantown's overall profit we would have to make the following calculations:

Contribution margin per unit for Lock Division = Selling price – Variable costs = $40 - $22 = $18

Contribution lost by lock division if Cabinet division buys from outside = $18 * 10,000 = $180,000

Cost per unit saved by Cabinet division = $40 - $36 = $4

Total cost saved by cabinet division = $4 * 10,000 = $40,000

Net decrease in profit = Contribution lost – Cost saved = $180,000 - $40,000 = $140,000

Therefore, the effect on Morgantown's overall profit is $140,000 decrease in Morgantown's profits.
