At $5 a bushel, there is an excess supply of wheat. Is this price above or below the equilibrium price?

If a mutual fund portfolio earned a return that exceeded the return on the S&P 500 stock index, you may conclude that the fu

Brums [2.3K]

Answer:

The correct answer is letter "A": True.

Explanation:

Risk-adjusted return is a measurement of risk for an investment or portfolio. It involves comparing the return of the investment or portfolio against the benchmark which is the overall performance of the market (typically compared with the S&P 500 index). For that purpose, the approach makes use of indicators such as the alpha, beta or standard deviation. Beta measures how correlated is the movement of a security according to the overall market movement. If a stock exceeds the return of the S&P 500 index, it means it is outperforming the market.

DL variances

diamong [38]

Answer:

Logen Construction

a. Standard hours for July Production = 3,350

b. Actual hourly wage rate = $18.25

c. Direct labor variances:

i. Labor Rate Variance = $827.50 U

ii. Labor Efficiency Variance = $720 F

iii. Total Labor Variance = $107.50 U

Explanation:

a) Data and Calculations:

Direct labor hours per frame = 5 hours

Standard hourly labor rate = $18

Standard direct labor cost per frame = $90 ($18 * 5)

Number of frames produced in July = 670

Actual direct labor hours = 3,310

Actual wages earned by workers = $60,407.50

a. Standard hours for July Production = Actual production unit multiplied by standard hours per unit

= 3,350 (670 * 5) hours

b. Actual hourly wage rate = Actual direct labor cost divided by actual direct labor hours

= $18.25 ($60,407.50/3,310)

c. Direct labor variances:

i. Labor Rate Variance = Standard direct labor rate - Actual direct labor rate * Actual direct labor hours

= $827.50 U ($18 - $18.25) * 3,310

ii. Labor Efficiency Variance = Standard direct labor hours - Actual direct labor hours * Standard Direct Labor Rate

= $720 F (3,350 - 3,310) * $18

iii. Total Labor Variance = Standard Direct Labor Cost - Actual Direct Labor Cost

= $107.50 U ($60,300 - $60,407.50)

Answer:

Any value given up from not choosing the other options is the opportunity cost

Explanation:

The cost of opportunity is the alternative that you sacrifice when you choose an option.

It represent the benefits that you misses out on when choosing one alternative over another.

In this case, the cost of opportunity is to plant crops.

A monopolist finds that a person’s demand for its product depends on the person’s age. The inverse demand function of someone of

KiRa [710]

Explanation:

A manufacturer of computer memory chips produces chips in lots of 1000. If nothing has gone wrong in the manufacturing process, at most 7 chips each lot would be defective, but if something does go wrong, there could be far more defective chips. If something goes wrong with a given lot, they discard the entire lot. It would be prohibitively expensive to test every chip in every lot, so they want to make the decision of whether or not to discard a given lot on the basis of the number of defective chips in a simple random sample. They decide they can afford to test 100 chips from each lot. You are hired as their statistician.

There is a tradeoff between the cost of eroneously discarding a good lot, and the cost of warranty claims if a bad lot is sold. The next few problems refer to this scenario.

Problem 8. (Continues previous problem.) A type I error occurs if (Q12)

Problem 9. (Continues previous problem.) A type II error occurs if (Q13)

Problem 10. (Continues previous problem.) Under the null hypothesis, the number of defective chips in a simple random sample of size 100 has a (Q14) distribution, with parameters (Q15)

Problem 11. (Continues previous problem.) To have a chance of at most 2% of discarding a lot given that the lot is good, the test should reject if the number of defectives in the sample of size 100 is greater than or equal to (Q16)

Problem 12. (Continues previous problem.) In that case, the chance of rejecting the lot if it really has 50 defective chips is (Q17)

Problem 13. (Continues previous problem.) In the long run, the fraction of lots with 7 defectives that will get discarded erroneously by this test is (Q18)

Problem 14. (Continues previous problem.) The smallest number of defectives in the lot for which this test has at least a 98% chance of correctly detecting that the lot was bad is (Q19)

(Continues previous problem.) Suppose that whether or not a lot is good is random, that the long-run fraction of lots that are good is 95%, and that whether each lot is good is independent of whether any other lot or lots are good. Assume that the sample drawn from a lot is independent of whether the lot is good or bad. To simplify the problem even more, assume that good lots contain exactly 7 defective chips, and that bad lots contain exactly 50 defective chips.

Problem 15. (Continues previous problem.) The number of lots the manufacturer has to produce to get one good lot that is not rejected by the test has a (Q20) distribution, with parameters (Q21)

Problem 16. (Continues previous problem.) The expected number of lots the manufacturer must make to get one good lot that is not rejected by the test is (Q22)

Problem 17. (Continues previous problem.) With this test and this mix of good and bad lots, among the lots that pass the test, the long-run fraction of lots that are actually bad is (Q23)

The supply curve represents the _____ price at which a firm is willing to _____.

Harrizon [31]

The supply curve represents the lowest price at which a firm is willing to accept. The supply curve shows the lowest price the producer is willing to accept for a unit of their product. Producers need to make sure they aren't losing money but selling their products to wholesalers to then sell to the consumer. The producer needs to make a profit off of their product as well. This is where the supply curve comes in, it allows the firm to set the lowest price they can accept when they sell their units off.
