A paper described a survey of 501 undergraduate students at a state university in the southwestern region of the United States. Each student in the sample was classified according to class standing (freshman, sophomore, junior, or senior) and body art category (body piercings only, tattoos only, both tattoos and body piercings, no body art).
Use the data in the accompanying table to determine if there is evidence of an association between class standing and response to the body art question. Assume that it is reasonable to regard the sample of students as representative of the students at this university. Use
α = 0.01.
| Body Piercings Only |
Tattoos Only |
Both Body Piercing and Tattoos |
No Body Art |

|---|---|---|---|---|
| Freshman | 62 | 7 | 15 | 86 |
| Sophomore | 44 | 11 | 10 | 65 |
| Junior | 20 | 9 | 7 | 46 |
| Senior | 21 | 17 | 24 | 57 |

Scenario: The IT leadership team has determined that the college will add another satellite campus.
Students will be allowed to connect to the network from personally-owned mobile devices. Troubleshooting services will be limited for the students so you must provide a Bring Your Own Device (BYOD) best practice guideline for students to help them manage their personal mobile devices. Your task is creating document demonstrating how to configure the mobile device settings as followstaking screenshotsto demonstrate your knowledge:
Android or Apple:
Paste screenshots into a Microsoft® Word document to demonstrate you applied appropriate configurations, and provide a 350-word narrative using Microsoft® Word to assist the student in applying appropriate settings to their device.

Twenty five high school students complete a preparation program for taking the SAT test. Here are the SAT scores from the 25 students who completed the SAT prep program: 434 694 457 534 720 400 484 478 610 641 425 636 454 514 563 370 499 640 501 625 612 471 598 509 531 The mean of these scores is 536.00. We know that the population average for SAT scores is 500 with a standard deviation of 100. The question is, are these students’ SAT scores significantly greater than a population mean of 500 with a population standard deviation of 100 ? Note that the the maker of the SAT prep program claims that it will increase (and not decrease) your SAT score. So, you would be justified in conducting a one-directional test. (alpha = .05).
Choose between
A - The prep program didn't result in significant improvement in SAT scores
B- The prep program resulted in significant improvement in SAT scores

Please walk me through SPSS setup and complete the following, NOT just answer it, but show me how you did it on SPSS
Below are data for the number of students in each of four age groups that are enrolled in several local schools:
|
Age Group |
Franklin School |
Lowell Public School |
JeanneD’arc School |
International School |
|
Toddlers (1 – 4 yrs.) Pre-adolescents (5 - 8 yrs.) Adolescents (9 - 12 yrs.) Teens (13 - 18 yrs.) |
0 56 131 0 |
36 52 51 64 |
0 24 98 111 |
34 41 52 69 |
Using SPSS, create a separate Pie Chart of the age groups for each school. Which school has the largest percentage of pre-adolescents? Then create of Bar Graph of the total count of students in each age group that are enrolled in local schools (including the local International School). Which age group represents the largest percentage of local students?

A survey conducted of 1,000 college students asked those who regularly drink alcohol, how many alcoholic beverages they consume each week. From this survey, on average (mean), these students consume five beverages each week. These data are normally distributed. The mean, median and mode are equal, and the standard deviation is 1.
1. How many of these students consume five or more alcoholic beverages each week?
2. What is the probability that a student in this study will consume five or more alcoholic beverages each week? (decimal)
3. How many of these adolescents consume five or less alcoholic beverages each week?
4. What is the probability that a student in this study will consume five or less alcoholic beverages each week? (decimal)
5. How many of these adolescents consume between four and six alcoholic beverages each week? 6. What is the probability that a student in this study will consume from four to six alcoholic beverages each week? (decimal)

Pretend that I (your professor) have enough free time to create an elaborate database for one of my fall face-to-face classes that contained the following information:
1) daily attendance
2) grades for every assignment and exam (including date of assignment)
3) age of students
4) every contact that each student made with me including email and office visit
5) voluntary class participation per student
6) whether students were freshmen, sophomore, junior, or senior
7) how many hours each student worked at a job each week
Write a 300-word essay discussing what ways I (the professor) could examine the relationship of this data to learn more about this class. Also, is there any additional data that would be interesting to have to examine this class?
Example: "I would like to analyze the relationship between class attendance and grade. I suspect that, on average, the students who do not show up to class are less likely to perform well..."

Dr. Nicole Ergo is a professor of accounting at Becker University, i.e. an employer of Dr. Ergo. He has often scheduled to meet with his doctoral students at his house with four rooms. In his house, Dr. Ergo has dedicated two rooms for business related to classes he teaches. In these rooms, five computers are installed with electronic databases and statistic software, such as SPSS and SAS for doctoral students to carry out their research projects under the supervision of Dr. Ergo. Dr. Ergo has an office on campus but his office is too small to accommodate five computers and his doctoral students. Dr. Ergo calls you to determine whether he could deduct expenses related to his home office. Your memo should include a discussion of Section 280A.
