Suppose a farmer wanted to test the effectiveness of three different types of fertilizer on strawberry production: no fertilizer, organic fertilizer, and non-organic fertilizer. Three sections of strawberry fields are selected, a random sample of 5 strawberry plants from each section are selected at the end of the growing season. The number of strawberries produced on each plant is counted. The purpose of the study is to determine if type of fertilizer affects strawberry production. Is there a significant effect of fertilizer on strawberry production?
a.Write out the null and alternative hypothesis for this study.
No Fertilizer Organic Fertilizer Non-organic fertilizer

Wilhelms Cola Company plans to market a new lime-flavored cola this summer. The decision is whether to package the cola in returnable or non-returnable bottles. Currently, the legislature is considering eliminating nonreturnable bottles. The CEO of Wilhelms has discussed the problem with state legislators and established that there is a 50-50 chance that returnable bottles will be eliminated. The following table has been created to show estimated monthly profits in returnable vs nonreturnable bottles.
| Law Passed (s1) | Law Not Passed(s2) | |
| Returnable Bottles | 80 | 40 |
| Non Returnable Bottles | 25 | 60 |
1. Compute the expected opportunity loss for returnable bottles. Round to one decimal.
2. Compute the expected opportunity loss for non-returnable bottles. Round to one decimal.
3. Compute the expected value of perfect information. Round to one decimal

Sheridan, Ltd. has 8,000 outstanding no par value $1.00
preferred shares issued for $80,000 and 37,000 outstanding no par
value common shares issued for $22,200.
No dividends were paid or declared during 2020 and 2021. Sheridan
wants to distribute $44,616 in dividends on December 31, 2022.
a) Calculate the amount of dividends to be paid to each group of shareholders (i.e., preferred and common), assuming the preferred shares are non-cumulative and non-participating.
| Preferred | Common | |||
| Total dividends | $ | $ |
b) Calculate the amount of dividends to be paid to each group of shareholders (i.e., preferred and common), assuming the preferred shares are cumulative and non-participating.
| Preferred | Common | |||
| Total dividends | $ | $ |
c) Calculate the amount of dividends to be paid to each group of shareholders (i.e., preferred and common), assuming the preferred shares are cumulative and fully participating.

Your HR Director presents you the following data on your employees from a regression output
Dependent variable: Wage and Salary Income (INCWS)
Independent variable: a disability affecting work indicator
--------------------------------------------------------------------------------------------------
INCWS | Coefficient Std. Err. t P>|t| Beta
-------------+------------------------------------------------------------------------------------
Work Disability | -9303.723 4475.500 -2.079 0.038 -0.070
constant | 37931.813 1416.073 26.787 0.000

Write the regression equation for the above output.
What information does the constant give you?
What information does the slope of the coefficient give you?
Write the null and alternative hypotheses to test whether or not disabled people earn less than non-disabled people.
At the 5% significance level, do disabled people earn less than non-disabled people?
At the 1% significance level, do disabled people earn less than non-disabled people?

In human beings, the gene for red green colorblindness (r) is sex linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled.
a. What is the genotype of the woman's father? b. What is the probability that the couple's first child will be a non-freckled, normal visioned girl c. What is the probability that the first two children born to the couple will be freckled and colorblind girls? d. What is the probability that the first child born to the couple will either be a freckled, colorblind boy or a non freckled, normal visioned girl or a non-freckled, normal visioned boy e. What is the probability that the first four children born to the couple will be freckled and normal visioned girls?

But when it comes to the non-profit versus for-profit business how do they compare? Your assignment is to analyze this using a comparison format. Let’s see which side you are on. In 500 words or more, answer the questions listed below. How do their objectives differ? How do they generate revenue? How do they control and report expenses/expenditures? How do they measure and report profit? How is equity and ownership reported? Reflect on your future career goals as an accountant. It is obvious that both non-profit and for-profit businesses need accountants; but, how does their focus and job differ? Do non-profit businesses pay competitively to for-profit businesses? Now that you have compared the two business types and the role accountants play along with their compensation, where do you see yourself fitting and why?

Which of the following statements is true? Note that more than one of the statements may be true.
a. Every relation that is in 3NF is in 2NF.
b. A relation that is in 2NF, and that has a non-primary-key attribute that is functionally dependent on another non-primary-key attribute is not in 3NF.
c. A relation that is in 2NF, and that has a non-primary-key
attribute that is transitively functionally dependent on the
primary key is not in 3NF.
Which of the following statements is true? Note that more than one of the statements may be true.
a. If A → B and C → D then B ∪ D is fully functionally dependant on A ∪ C, where X ∪ Y means the merge (or union) of X and Y.
b. If A → B and C→ D then A ∪ C→ B ∪ D, where X \cup∪ Y means the merge (or union) of X and Y.
c. If A is fully functionally dependant on B then B is fully functionally dependant on A.
d. If A → B then B → A.

In this module we have learned that the innate or non-specific immune response provides the body's first and second lines of defense against invading pathogens. This part of the immune system is not damaged in AIDS. It might be helpful to educate AIDS patients on the innate immune system to help them understand what is going on in their bodies, and how to make the most of it. or this discussion, choose one example of innate immunity to focus on. Choose one aspect that was particularly interesting to you. Do some online research to find out a little more about it. Here is a list of examples, but you can think of other ones as well.
1) Tell us how an AIDS patient can work with his/her non-specific pathways to help them work to their optimal capacity. For example, how can he/she work WITH his non-specific inflammatory response to get optimal benefit?
