Consider the following hypothesis test.

H₀: σ₁² = σ₂²

H_a: σ₁² ≠ σ₂²

(a)

What is your conclusion if

n₁ = 21, s₁² = 8.2, n₂ = 26, and s₂² = 4.0?

Use α = 0.05 and the p-value approach.

Find the value of the test statistic.

Find the p-value. (Round your answer to four decimal places.)

State your conclusion.

(b)

Repeat the test using the critical value approach.

Find the value of the test statistic.

State the critical values for the rejection rule. (Round your answers to two decimal places. If you are only using one tail, enter NONE for the unused tail.)

test statistic≤ ______

test statistic≥ ______

State your conclusion.

Twelve chairs are to be painted. The available colors are Red, Blue, Green, and Yellow, and every chair must be painted with one color. Assuming that all coloring schemes are equally likely, what is the probability that one color is not used and there are at least two chairs of every other color ? (The answer is 0.25) Can anyone explain to me why ?

In tomatoes, yellow flowers (Wf) are dominant over white flowers (wf), and yellow fruit (r) are recessive to red fruit (R). A cross was made between true-breeding plants with yellow flowers and yellow fruit, and plants with white flowers and red fruit. The F1 generation plants were then crossed to plants with white flowers and yellow fruit. The following results were obtained:

75 white flowers, red fruit

205 white flowers, yellow fruit

216 yellow flowers, red fruit

37 yellow flowers, yellow fruit

a. What is the genotype of the F1 plant? Please write your answer is such a way that you show which alleles are present on each homologous chromosome. (3 points)

b. How many plants with yellow flowers and yellow fruit should we have expect to observe from these results? (3 points)

c. In testing to determine if these two traits are linked, what is the chi-square statistic associated with the test of independence? (3 points)

d. What are the degrees of freedom and probability associated with this statistic? Are these two traits linked? (3 points)

e. What is the distance in terms of map units between the two genes that control these traits? (3 points)

Company H&R BLOCK

Be sure to provide a link to the financial statements. You must use the annual report, from the H &R Block website, or from the SEC database. Quarterly financial statements should not be used to do ratios because (1) many companies are seasonal and quarterly numbers may not be representative of annual performance and (2) quarterly numbers are not audited, whereas annual financials are. Financial information provided by third parties like Yahoo Finance or Google Finance are not acceptable, as these numbers are not necessarily accurate. You must use H & R Blocks official annual report. If you go to H& R Blocks website, and select investor section, annual reports, or SEC filings and you should get the correct information (which also might be in the form of a 10K report)

Show the ratio calculation for each year, the calculation result, and the interpretation of the numbers. I suggest you put it in tabular format and cut and paste into discussion to maintain formatting Do not post as an attachment.

What do you note in the changes of ratios from year to year? Explain what the ratios mean. Do these ratios correlate with what you know about these companies? Be sure to provide the raw data so we can see how you calculated these ratios. Do not use calculated ratios you might find on financial websites. They are often incorrect or use old data.

1. Gross Profit margin

2. Profit Margin

3. Debt Ratio ( Liabilities/Assets)

4. Quick Ratio

Please be sure to use H&R Block as the company!
