What are “first principles”? What have been some of the first principles (or causes) that have been put forth in different cultures to explain the existence of the universe? Why would it be important to establish or agree upon “first principles” before discussing any topic in philosophy, including cosmology?

Members of the board of directors of Security First Security First have received the following operating income data for the year ended: May 31, 2018:

Members of the board are surprised that the industrial systems product line is not profitable. They commission a study to determine whether the company should drop the line. Company accountants estimate that dropping industrial systems will decrease fixed cost of goods sold by $ 80,000 and decrease fixed selling and administrative expenses by $ 10,000.

Read the requirements:

1. Prepare a differential analysis to show whether Safety Point Safety Point should drop the industrial systems product line.

2. Prepare contribution margin income statements to show Safety Point's Safety Point's total operating income under the two alternatives: (a) with the industrial systems line and (b) without the line. Compare the difference between the two alternatives' income numbers to your answer to Requirement 1.

3. What have you learned from the comparison in Requirement 2?

1.) First answer = first blank; second answer = second blank. The test statistic for an ANOVA is a ratio of values and is noted by (F). In independent- measures ANOVAs, ________ comprises the numerator of this ratio, whereas ________ comprises the denominator of this ratio.

A: systematic treatment effects and unsystematic effects; unsystematic effects

B: systematic treatment effects; unsystematic effects

C: unsystematic effects; systematic effects and unsystematic effects

D: unsystematic effects; systematic effects

3.) Please select all that apply. There may be multiple answers. Which of the following applies to Type II Errors for any given hypothesis test?

A: Type II Errors influence the power of hypothesis tests

B: the probability of a Type II Error is known as beta (β)

C: the probability of a Type II Error is known as alpha (α)

D: they occur when a researcher erroneously fails to reject a false null hypothesis (false negative)

E: they occur when a researcher erroneously rejects a true null hypothesis (false positive)

4.) Please select all that apply. There may be multiple answers. Which of the following are assumptions of independent-measures t-tests?

A: all of the observations must be dependent on one another

B: the populations that were sampled from must be normally distributed

C: the populations that were sampled from must have equal variances (homogeneity of variance)

D: the populations that were sampled from must have unequal variances (heterogeneity of variance)

E: all of the observations must be independent of one another F: the scores between treatment conditions must be consistent (homogeneity of covariance)

5.) Type either "test-wise" or "experiment-wise" for each blank below. Please mind your spelling; add the - also)! A researcher runs three separate t-tests in order to evaluate a single hypothesis concerning three doses of an experimental drug. The researcher sets the alpha-level of each t-test at 0.05. In this scenario, 0.05 is the ________ α-level and 0.15 is the ______ α-level.

6.) In which situation will an F-ratio (F-statistic) be the LARGEST value?

A: when systematic sources of variability are high and unsystematic sources of variability are high

B: when systematic sources of variability are low and unsystematic sources of variability are low

C: when systematic sources of variability are low and unsystematic sources of variability are high

D: when systematic sources of variability are high and unsystematic sources of variability are low

7.) Please select all that apply. There may be multiple answers. Which of the following are assumptions of one-way, repeated-measures ANOVAs?

A: the treatment effects must be consistent across subjects (homogeneity of covariance)

B: the population that was sampled from must be normally distributed

C: the variances of the population distributions for each treatment should be equivalent (homogeneity of variance)

D: the variances of the population distributions for each treatment should have unequal variances (heterogeneity of variance)

E: all of the observations must be independent of one another

F: ONLY the observations within each treatment must be independent
