Answer:

stock's returns = (0.16 - 0.09 + 0.23 + 0.24 + x) / 5 = 0.144

0.16 - 0.09 + 0.23 + 0.24 + x = 0.144 x 5

0.54 + x = 0.72

missing return (x) = 0.72 - 0.54 = 0.18 = 18%

variance = [(0.16 - 0.144)² + (-0.09 - 0.144)² + (0.23 - 0.144)² + (0.24 - 0.144)² + (0.18 - 0.144)²] / 5 = (0.000256 + 0.054636257 + 0.007396 + 0.009216 + 0.001296) / 5 = 0.014560051

standard deviation = √0.014560051 = 0.1207 = 12.07%

3) P-value: 0.597576

The test statistic is not significant and failed to reject the null hypothesis.

4) The test statistic is not significant. So, there is no evidence to conclude that there is a difference between groups.

zysi [14]

Answer:

Dr supplies expense   $4,100

Cr supplies                                       $4,100

Explanation:

Supplies used in the year needs to be ascertained before any adjusting entry can be posted.

Supplies used=beginning supplies+purchases-ending supplies

beginning supplies is $3,690

purchases of supplies was $1,700

ending balance of supplies was $1,290

supplies used=$3,690+$1,700-$1,290=$ 4,100.00  

The used portion of supplies would be debited to supplies expense while supplies inventory is credited with the same amount.

aleksandr82 [10.1K]

Answer:

d. Accounts payable and accruals are tied directly to sales.

Explanation:

Additional funds needed method determines the amount that the company needs to finance the increase in total sales.

In response to the increase in sales, the company has to increase its assets to achieve that goal. The increase in total assets is partly offset by an increase in liabilities and the other part is offset by an increase in retained earnings.

Suppose that there are two independent economic factors, F1 and F2. The risk-free rate is 3%, and all stocks have independent fi
yarga [219]

Answer:

Rp = 3% + BP1 * 10.42% + BP2 * 6.1%

Explanation:

Portfolio A:

R_p = R_f + Beta1*Factor1 + Beta2*Factor2

32% = 3% + 1.6*F1 + 2*F2

Portfolio B

29% = 3% + 2.6*F1 - 0.2*F2

Solvig the equatios

3% = -F1 + 2.2*F2

F1 = 2.2F2 - 3%

F1 = 2.2F2 - 0.03

Substituting

29% = 3% + 2.6*(2.2F2 - 0.03) - 0.2F2

29% = 3% + 5.72F2 - 0.078 - 0.2F2

5.52F2 = 29% - 3% +0.078

5.52F2 = 0.26 +0.078

5.52F2= 0.338

F2 = 0.338/5.52 = 0.061

F1 = 2.2F2 - 0.03 = 2.2(0.061) - 0.03

    = 0.1042

The return Beta relationship in this economy  Rp = 3% + BP1 * 10.42% + BP2 * 6.1%
