1. Historically, women were less likely to invest in a college degree than men. Why was this the case? What has changed to reverse this trend?

2. Explain the economics underlying the human capital investment decision (specifically, the decision to go to college versus sticking with just the high school diploma).

3. Empirical evidence shows clearly that, on average, individuals with more years of education earn more money, other things equal. Two different theories support this evidence: human capital theory and signaling theory. Explain both theories.

4. Describe the trends over time in (a) educational attainment by gender; and (b) percentage of graduates in selected professional degree programs that are female. Then provide reasons for the particular significance of the 1970s in these trends. 5. Describe the trend since 1974 in the college wage premium and the gender difference in this trend.

Acme Materials is a publicly traded company on the NYSE. On October 15, 2021, at 10:46am, company ACME materials, has traded between the price range of $2400 and $2300. Where, $2400 is the high of the range and $2300 is the low of the range.

Fact: As of 10:46am,

- There is a 75% probability that either $2400 will be thehighest price of the day

or

$2300 will be the lowest price of the day.

(Meaning there is a 25% probability that neither 2400 or 2300 will be the high or low of the day.)
Probability of both events occuring together is not provided

Question 1: What is the probability that $2400 is the highest price of the day?

Question 2: Please list / define, what statistical principles and or formula’s make this answer true? How do I get to understandthis answer?

Question 3: I have basic high school math skills, what resourcescan I use to further my understanding of the underlying principles to this solution?

(a) Farmer Sherry can grow wheat and barley. She can grow 75 bushels of wheat
or 125 bushels of barley on a hectare of her land for the same cost. The price of wheat is $2 per bushel
and the price of barley is $0.80 per kilogram. Show the benefits to Sherry of specialization. What should
she specialize in? Why ? (2)
(b) You work as a teacher at your school, making $15 per hour. Yesterday, you decided to cancel your two-
hour tutoring appointment in order to meet friends for a coffee. The coffee cost you $3.50. What was the
opportunity cost of this decision in dollars? Explain your solution! (2)
(c) Give two examples of each of the following: (4)
(i) Positive economic statement, (ii) Normative statement (iii) Micro Economics (iv) Macro Economics

I need the answer explained and computer typer so I can read it! thank you

For a simple linear regression model yi= α + βxi + ui , i = 1

1- Suppose researchers want to know the effect of elementary school class size on students’ math scores(total score is 100), intuitively they think there exists a negative linear relationship between class size and students’ math scores. The researchers want to know the marginal effect of class size on student’s math scores.

1-1) Based on the background information, design an linear regression model for this research question, and briefly explain your dependent variable, independent variable, and the meaning of the parameters.

1-2) Briefly explain the assumptions of the classical linear regression model (CLRM)

1-3) Suppose the assumptions of the CLRM are satisfied, what properties of your estimators should be expected to have?

PVR Cinemas decide to continue screening a super hit film released on 17 March 2020 for the next two month till 15 May 2020 as they expect the revenue to increase in the month of April & May due to school vacation. The management opened advance booking for the tickets and all the tickets got sold. The cinemas received ₹ 60 lacs in total revenue for this 60-day screening of the movie. How should the cinema’s accountant treat this revenue? Explain the accounting concept that will aid the accountant in this treatment.
(a) What is Accrual Accounting? How does it differ from the Cash basis of Accounting?

(a) How are common size statements useful to the analyst?

Is your electric blanket safe? It has been theorized that excess nighttime exposure to electromagnetic fields may reduce the production of the hormone melatonin in certain women. Furthermore, reduced melatonin levels might lead to an increased risk of breast cancer. Scott Davis at Seattle's University of Washington School of Public Health and Community Medicine was one of the first to investigate links between electromagnetic fields and cancer (particularly leukemia). He has been quoted as saying, "Electric blankets were pretty effectively re-engineered a number of years ago. Modern-day electric blankets ? anything you buy in the store now ? (has a different) configuration of the heating elements in the blanket so that it doesn't produce any magnetic fields." How could the wiring in an electric blanket be designed to minimize or eliminate the production of external magnetic fields?

At Rochester Institute of Technology, 34% of the students are female. The Department of Mathematics and Statistics would like to know if the Data Analysis course has a different percentage of female students. From a random sample of 50 students taking this course, 23 were female. Does this data support that the proportion of females taking this class is different from the percentage of females in the school?

The appropriate hypotheses would be:

A) H o μ = 34 a n d H A μ ≠ 34

B) H o p = 0.34 a n d H A p ≠ 0.34

C) H o p ≤ 0.34 a n d H A p > 0.34

D) H o p ≥ 0.34 a n d H A p < 0.34

Answer: A, B, C, D?

The Test Statistic would be:?

The P-value would be:?   

The Conclusion would be:?

What do you think about competitive academic activities, such as spelling bees, focusing on the following questions:

(1) Do spelling bees and other academic competitions encourage or discourage working hard?

(2) What are the effects on self-concept and self-esteem for the few winners and the many losers?

(3) Do these events encourage a mastery orientation, a learned-helpless approach, or both?

(4) What types of comments can teachers make if they want to offer process praise rather than person praise for students’ performance in academic competitions?

(5) Do students think that competitive school activities should be eliminated? Why or why not?

(6) How would you suggest modifying the structure of spelling bees and other competitive academic activities so that they encourage cooperation among children, rather than just competition?

1) Rising worker productivity means that more workers are demanded, other things being equal. When workers have access to better tools, they can produce more, and when they produce more, they become more valuable to their companies. If this works, then why do some people oppose technological progress, fearing that better technology will lead to less, not more, jobs being created?

2) Suppose that you have a choice between two options. Option A - you can study four years in the world’s best university, but you are not allowed to tell anyone that you have studied there. Option B - after 4 years of never once attending the world’s best university, you will get the diploma from this school and you can display it whenever and however you please. Which of these options would enhance your future earnings more and why?
