Answer:

The common problem i encounter mostly is the statistical modelling problem.

In this scenario we choose best combination of independent variables for the hypothesis testing. the independent variable shows the significant effect on dependent variable so we keep it in modelling.

My null hypothesis would be that there is no significant effect of independent variable on dependent variable.  for my alternative hypothesis there exist is significant effect of independent variable on dependent variable.

Explanation:

Solution

The common problem I face daily is the statistical modelling problem which is the selection of relevant independent variable for prediction modelling.

In this example to select the best combination of independent variables we use hypothesis testing. if the independent variable has significant effect on dependent variable then the independent variable shows the significant effect on dependent variable so we keep it in modelling. In this way the model gets improved.

Since there are always two variables or two categories. hence it has a two sample test.

The Hypothesis can be shown below:

Null hypothesis:

H0:There is no significant effect of independent variable on dependent variable.

Alternative hypothesis:

Ha: There is significant effect of independent variable on dependent variable.

Pacor Industries recently paid its annual dividend of $2. Dividends have consistently grown at a rate of 2.2%. Analysts estimate
yulyashka [42]

Answer:

The intrinsic value of the stock is $21.52

Explanation:

To calculate the intrinsic value of the stock, we will use the constant growth model of the dividend discount model (DDM). The DDM values the stock based on the present value of the expected future dividends from the stock. The formula for price today under the constant growth model of DDM is,

P0 = D0 * (1+g) / r - g

Where,

  • D0 * (1+g) is D1 or the next expected dividend
  • r is the required rate of return
  • g is the growth rate in dividends

First of all, we need to calculate the r or required rate of return using the CAPM equation,

r = rRF + Beta * (rM - rRF)

Where,

  • rRF is the risk free rate
  • rM is the return on market

r = 0.024 + 1.12 * (0.107 - 0.024)

r = 0.11696 or 11.696%

P0 = 2 * (1+0.022) / (0.11696 - 0.022)

P0 = $21.52

McCann Co. has identified an investment project with the following cash flows.
Shalnov [3]

Answer:

Explanation:

Cash flow is 530 , 690 , 875 and 1090 in 1st to 4 th year respectively

discount rate = 10 %

NPV = 530/ 1.10 + 690 / (1.10)² + 875/(1.10)³ + 1090/ (1.10)⁴

= (530x1.10³ + 690 x 1.10² + 875x 1.10 + 1090)/ 1.10⁴

= (705.43 x  +834.9 +962.5 +1090)1.10⁴

= 3592.83 / 1.10⁴

= 2453.95

Discount rate 18%

NPV = 530/ 1.18 + 690 / (1.18)² + 875/(1.18)³ + 1090/ (1.18)⁴

= (530x1.18³ + 690 x 1.18² + 875x 1.18 + 1090)/ 1.18⁴

= (870.80696 +960.756 +1032.5 +1090)1.18⁴

= 2039.46

Discount rate 24%

NPV = 530/ 1.24 + 690 / (1.24)² + 875/(1.24)³ + 1090/ (1.24)⁴

= (530x1.24³ + 690 x 1.24² + 875x 1.24 + 1090)/ 1.24⁴

1010.51072+ 1060.944+1085+1090 / 1.24⁴

= 1796.14
