Open the files for the Course Project and the data set.
For each of the five variables, process, organize, present, and summarize the data. Analyze each variable by itself using graphical and numerical techniques of summarization. Use Excel as much as possible, explaining what the results reveal. Some of the following graphs may be helpful: stem-leaf diagram, frequency/relative frequency table, histogram, boxplot, dotplot, pie chart, and bar graph. Caution: not all of these are appropriate for each of these variables, nor are they all necessary. More is not necessarily better. In addition, be sure to find the appropriate measures of central tendency, the measures of dispersion, and the shapes of the distributions (for the quantitative variables) for the above data. Where appropriate, use the five number summary (the Min, Q1, Median, Q3, Max). Once again, use Excel as appropriate, and explain what the results mean. Analyze the connections or relationships between the variables. There are 10 possible pairings of two variables. Use graphical as well as numerical summary measures. Explain the results of the analysis. Be sure to consider all 10 pairings. Some variables show clear relationships, whereas others do not. Report Requirements From the variable analysis above, provide the analysis and interpretation for three individual variables. This would include no more than one graph for each, one or two measures of central tendency and variability (as appropriate), the shapes of the distributions for quantitative variables, and two or three sentences of interpretation. For the 10 pairings, identify and report only on three of the pairings, again using graphical and numerical summary (as appropriate), with interpretations. Please note that at least one pairing must include a qualitative variable, and at least one pairing must not include a qualitative variable. Prepare the report in Microsoft Word, integrating graphs and tables with text explanations and interpretations. Be sure to include graphical and numerical back up for the explanations and interpretations. Be selective in what is included in the report to meet the requirements of the report without extraneous information. All DeVry University policies are in effect, including the plagiarism policy. Project Part A report is due by the end of Week 2. Project Part A is worth 100 total points. See the grading rubric below. Submission: The report, including all relevant graphs and numerical analysis along with interpretations Format for report: Brief Introduction Discuss the first individual variable, using graphical, numerical summary and interpretation. Discuss the second individual variable, using graphical, numerical summary and interpretation. Discuss the third individual variable, using graphical, numerical summary and interpretation. Discuss the first pairing of variables, using graphical, numerical summary and interpretation. Discuss the second pairing of variables, using graphical, numerical summary and interpretation.

Arndt, Inc., reported the following for 2018 and 2019 ($ in
millions):
| 2018 | 2019 | ||||||
| Revenues | $ | 893 | $ | 992 | |||
| Expenses | 764 | 804 | |||||
| Pretax accounting income (income statement) | $ | 129 | $ | 188 | |||

beginning in 2020. Prepare a schedule that reconciles the
difference between pretax accounting income and taxable income.
Using the schedule, prepare the necessary journal entry to record

A researcher hypothesizes that people who believe in paranormal phenomena will obtain higher scores on the personality dimension of openness-to-experience. To test this belief, the researcher takes 8 randomly-selected people and gives them 2 tests: one is a 50-item test that measures the extent to which they endorse beliefs in paranormal phenomena and the other is a 30-item test that measures their openness-to-experience. The following data were obtained:
| Subjects | Paranormal beliefs | Openness-to-experience |
| 1 | 40 | 22 |
| 2 | 20 | 14 |
| 3 | 48 | 24 |
| 4 | 6 | 9 |
| 5 | 30 | 23 |
| 6 | 26 | 20 |
| 7 | 42 | 27 |
| 8 | 12 | 7 |
a) Do these data provide significant support for the researcher’s belief (α = .05)?
b) Use the data to generate a 95% prediction interval for the openness-to-experience score of a person with a paranormal beliefs score of 25.

For each of the following tests of hypotheses, determine whether the null hypotheses should be rejected. Use the classical method by finding the lower xL and upper xU limits for two-tail tests (or one of the two for a one-tail test). Additionally, don't forget to use a t-value (rather than a z-value) when n<30.
A) Ho: µ = 6,000 Ha: µ ≠ 6,000; n = 70; x = 6,150; σ = 2,600; α = .01
B) Ho: µ = 50 Ha: µ > 50; n = 24; x = 55; s = 7; α = .05
C) Ho: µ ≥ 400 Ha: µ < 400; n = 56; x = 350; s = 62; α =.03
