A production facility employs 10 workers on the day shift, 8 workers on the swing shift, and 6 workers on the graveyard shift. A quality control consultant is to select 4 of these workers for in-depth interviews. Suppose the selection is made in such a way that any particular group of 4 workers has the same chance of being selected as does any other group (drawing 4 slips without replacement from among 24).

Answers

Answer 1

Answer:

The answer is below

Explanation:

A What is the probability that all 4 selected workers will be the day shift?

B What is the probability that all 4 selected workers will be the same shift?

C What is the probability that at least two different shifts will be represented among the selected workers.

A)

The total number of workers = 10 + 8 + 6 = 24

The probability that all 4 selected workers will be the day shift is given as:

[tex]P_a=\frac{C(10,4)}{C(24,4)}= \frac{210}{10626}=0.0198[/tex]

[tex]C(n,r)=\frac{n!}{(n-r)!r!}[/tex]

B) The probability that all 4 selected workers will be the same shift ([tex]P_B[/tex]) = probability that all 4 selected workers will be the day shift + probability that all 4 selected workers will be the swing shift + probability that all 4 selected workers will be the graveyard shift.

Hence:

[tex]P_B=\frac{C(10,4)}{C(24,4)}+\frac{C(8,4)}{C(24,4)}+\frac{C(6,4)}{C(24,4)}=0.0198+0.0066+0.0014=0.0278[/tex]

C) The probability that at least two different shifts will be represented among the selected workers ([tex]P_C[/tex])= 1 - the probability that all 4 selected workers will be the same shift([tex]P_B[/tex])

[tex]P_C=1-P_B\\\\P_C=1-0.0278\\\\P_C=0.972[/tex]

B. Raising the number of treasury securities for sale
C. Increasing the interest rate on credit cards
D. Decreasing the total number of Federal Reserve banks

Answers

Answer:

A. Lowering the prime rate on bank loans

Explanation:

Prime rates are the interest rates that the commercial banks charge their most credit-worthy customers, mostly corporates. These customers are judged low-risk clients and get loans at lower interest rates compared to retail customers. If a commercial bank lowers the prime rate, the normal interest rates are also likely to decrease.

The discount rate is the interest rate at which commercial banks will means commercial banks are obtaining loans at an expensive rate. Consequently, they will charge customers a high-interest rate for loans advanced. If the Federal Reserve reduces the discount rate, banks will reduce interest rates on loans. The banks will be accessing credit from the Fed at lower interest rates.

Any type of insurance exists to reduce or completely remove the policyholder's liability. Hence option A is correct .

What is a filing a claim?

The medical expenses that the policy-holder might otherwise be responsible for as a result of an auto accident are covered by medical insurance in an auto policy.

When you make a claim, you ask an insurance provider to pay you a specific amount of money in accordance with the conditions of the insurance policy. The period of time after filing a claim during which a policyholder cannot receive insurance benefits is known as the elimination period.

A claims adjuster will get in touch with you after your claim is submitted. They can want you to fill out a Proof of Loss form. Your insurer's coverage amount will be determined by the adjuster, and assist you with the claims procedure.

There is no rule dictating how long you must wait before making a claim. You should get in touch with your insurance company as soon as an incident occurs. The longer you wait, the more damage may occur, depending on the sort of incident.
