d. Should the executive leave the house on the market for another month? Why or why not?

a.

Expert Solution

To determine

Obtain the mathematical expression for the probability density function.

Answer to Problem 39SE

The probability density function for sales price is,

f(x)={125,000 for 200,000≤x≤250,0000 elsewhere

Explanation of Solution

Calculation:

The executive’s employer offers to buy a house for $210,000 and this offer will be expired by the end of the week. Post discussion with business executive’s relator, the seller believes that by leaving the house in the market for another month, the price for house will be uniformly distributed between $200,000 and $225,000.

The probability density function for uniform distribution is,

f(x)={1b−a for a≤x≤b0 elsewhere

The probability density function for sales price is,

f(x)={125,000 for 200,000≤x≤250,0000 elsewhere

b.

Expert Solution

To determine

Find the probability that the house will get with at least $215,000.

Answer to Problem 39SE

The probability that the house will get with at least $215,000 is 0.4.

Explanation of Solution

Calculation:

The cumulative density function for uniform distribution is,

P(x≤X)=X−ab−a

The probability that the house will get with at least $215,000 is,

P(x>215,000)=1−P(x≤215,000)=1−215,000−200,00025,000=1−15,00025,000=0.4

Thus, the value of P(x>215,000) is 0.4.

c.

Expert Solution

To determine

Find the probability that the house will get less than $210,000.

Answer to Problem 39SE

The probability that the house will get less than $210,000 is 0.4.

Explanation of Solution

Calculation:

The probability that the house will get less than $210,000 is,

P(x<210,000)=210,000−200,00025,000=10,00025,000=0.4

Thus, the value of P(x<210,000) is 0.4.

d.

Expert Solution

To determine

Explain whether the executive can leave the house in the market for another month or not.

Explanation of Solution

Calculation:

If the house is left in market for another month, the average sales price of house is,

E(x)=a+b2=200,000+225,0002=425,0002=212,500

This indicates that if the executive leaves the house in the market for another month, then the expected sales price is $2,500 higher than the before price $210,000. If the house is left in the market for another month, the executive will get less than the company’s offer with 0.4 probability. It represents that the executive can leave the house in the market for another month with an excepted cost of $212,500.

Answer 34

Explanation of Solution

Calculation:

If the house is left in market for another month, the average sales price of house is,

E(x)=a+b2=200,000+225,0002=425,0002=212,500

This indicates that if the executive leaves the house in the market for another month, then the expected sales price is $2,500 higher than the before price $210,000. If the house is left in the market for another month, the executive will get less than the company’s offer with 0.4 probability. It represents that the executive can leave the house in the market for another month with an excepted cost of $212,500.
