If a calculated odds ratio is 1, it indicates:
a.
The outcome is the same in both groups
b.
There is not difference between groups
c.
The null hypothesis should be retained
d.
All of the above
Ratio Analysis - Explain how the following ratios are calculated
and what the ratio indicates. Include how these ratios provide
useful information related to accounting decision making topics
such as efficiency (collecting amounts owed to the firm, using the
assets well, getting items to market, etc.), liquidity (ability to
pay current debts), solvency (ability to pay long term or all
debts), etc. Please look at all the ratios not just these.

construct a persuasive argument for the value
(conditional probability, odds, odds ratio, etc.) that,
intuitively, makes the most sense for you to report as a result to
your audience. Be sure to provide a specific rationale for your
choice
3. The odds ratio will most closely approximate the risk ratio
from which of the following hypothetical cohort studies that have
the stated risks in the exposed and unexposed groups?
a. 1% risk of disease in the unexposed, 2% risk in the exposed
b. 5% risk of disease in the unexposed, 10% risk in the exposed c.
10% risk of disease in the unexposed, 20% risk in the exposed d.
20% risk of disease in the unexposed, 40% risk in...
1. A firm has a current ratio of 1.8 and a quick ratio of 0.6. This
indicates that:A. the firm has more current liabilities than it does current
assets.B. the firm buys inventory on credit.C. cash is the largest component of current assets.D. inventory represents more than 50 percent of the firm's
current assets.2. Which one of the following will increase the net working capital

what is an F ratio and how is it calculated?
2. If SSbetween = 30, SSwithin = 40, DFbetween =3, and
DFwithin = 20, then F = ?
3. If dfbetween =3, and DFwithin = 60, if alpha is set at .05,
then Fcrit= ?
4. if the sample size is 30 in the mean score for group one is

1. If the test statistic (the calculated F ratio) is 10 and the
error variance is 5, what is the treatment variance?
2. If the treatment Sum of Squares is 400, and k=5, what is the
treatment variance?
3. What is the table value for F(11,46) when alpha = .05?
4. What is the lowest possible value for the F statistic?
5. The following table shows the results of an analysis of
variance comparing three treatment conditions with a sample...
Researchers found a crude odds ratio of 1.8 in a case-control study. They stratified their analysis within levels of a binary potential confounder and found an odds ratio of 1.2 in one level of the confounder and an odds ratio of 2.8 in the other level of the confounder.
A. Do you think they should present the adjusted odds ratio in the report of their results?
B. Why or why not?
. Interpret the odds ratio to determine the strength of
association between the potential sources of exposure and the
disease. Tip: Use the data in Table 2 of the final project research
study to calculate the odds ratio. Show your work.
