Investment A has an expected return of 14% with a standard deviation of 4%, while investment B has an expected return of 20% wit

Alex

Answer:

d. rational investors could pick either A or B, depending on their level of risk aversion

Explanation:

In making investment decisions investors use various analysis to make an informed decision on which assets will suit their needs.

Two of such analysis are returns standard deviation.

Returns shows the percentage of original investment that is expected to come back as profit.

Standard deviation is the tendency of investment performance to deviate from a mean value.

The higher the standard deviation the more the risk of getting low returns or getting higher profit. This is well suited to risk takers.

The lower the standard deviation the less variance from a mean value, so risk averse investors will prefer this.

In the given scenario risk averse investors will prefer Investment A with expected return of 14% with a standard deviation of 4%. Because of the low standard deviation.

Risk takers will prefer investment B with expected return of 20% with a standard deviation of 9%. Because of the higher standard deviation.

The probability that a randomly selected education major received a starting salary offer greater than $52,350 is . The probabil

AveGali [126]

Answer:

1. 0.0808

2. 0.5371

3. 58.2%

Explanation:

The first part of the question, with the input data, is missing.

This is missing part:

Assume that X, the starting salary offer for education majors, is normally distributed with a mean of $46,292 and a standard deviation of $4,320

<h2>Solution</h2><h2 />

Question 1: The probability that a randomly selected education major received a starting salary offer greater than $52,350 is ________

Find the Z-score.

The Z-score is the standardized value of the random variable and represents the number of standard deviations the value of the random variable is away from the mean:

$Z-score=\dfrac{X-\mu}{\sigma}$

$Z-score=\dfrac{\$52,350-\$46,292}{\$4,320}=1.40$

$P(X>\$52,350)=P(Z>1.40)=P(Z$

The standard normal distribution tables give the cumulative probabilities as the cumulative area under the bell-shaped curve. P(Z>1.40) is the area under the curve that is to the right of Z = 1.40 or, what is the same, P(Z<-1.40) is the area to the left of Z = - 1.40.

Using the former, the table indicates P(Z>1.40) = 0.0808, which is 8.08%

Question 2: The probability that a randomly selected education major received a starting salary offer between $45,000 and $52,350 is _______.

Now you must find the area under the curve between the two Z-scores.

$Z(X=$45,000)=\dfrac{\$45,000-\$46,292}{\$4,320}=-0.30$

$Z(X=$52,350)=\dfrac{\$52,350-\$46,292}{\$4,320}=1.40$

Then, you must find the area between Z = -0.30 and Z = 1.40

That is P(Z<1.40) - P(Z < - 0.30) = P(Z > - 1.40) - P(Z < - 0.30)

= 1 - P(Z< -1.40) - P( Z < -0.30)

Now, you can work with the area under the curve to the left of Z = - 1.40 and to the left of Z = - 0.30.

From the corresponding table, that is: 1 - 0.0808 - 0.3821 = 0.5371

Question 3. What percentage of education majors received a starting offer between $38,500 and $45,000?

For X = $38,500:

$Z=\dfrac{\$38,500-\$46,292}{\$4,320}=-1.80$

For X = $45,000

Z = -0.3 (calculated above)

Then, you must find the area under the curve to the right of Z = - 1.80 and to the left of Z = - 0.3

P (Z > - 1.80) - P (Z < - 0.3)

1 - P (Z < - 1.80) - P (Z < - 0.3)

1 - 0.0359 - 0.3821 = 0.582 = 58.2%
