The school district recently adopted the use of e-textbooks, and the superintendent is interested in determining the level of satisfaction with e-textbooks among students and if there is a relationship between the level of satisfaction and student classification. The superintendent selected a sample of students from one high school and asked them how satisfied they were with the use of e-textbooks. The data that were collected are presented in the following table.

Table 1: Student Classification (N=128)

Questions

1. Of the students that were satisfied, what percent were Freshmen, Sophomore, Junior, and Senior? (Round your final answer to 1 decimal place).

2. State an appropriate null hypothesis for this analysis.

3. What is the value of the chi-square statistic?

4. What are the reported degrees of freedom?

5. What is the reported level of significance?

6. Based on the results of the chi-square test of independence, is there an association between e-textbook satisfaction and academic classification?

A high school physics teacher wondered if his students in the senior class this year will be more likely to go into STEM (Science, Technology, Engineering, Mathematics) majors than Social Science and Liberal Arts majors. He asked each of his 65 students about their first choice for major on their college applications and conducted a Chi-square test for goodness of fit with an alpha level of .05 to see if the number of students choosing each category differs significantly.

35 – STEM

20 – Social Sciences

10 – Liberal Arts

d. Calculate the degree of freedom and then identify the critical value (1 point total: .5 for df, .5 for critical value)

e. Compare the X² statistic with the critical value, then report the hypothesis test result, using “reject” or “fail to reject” the null hypothesis in the answer (1 point total, .5 for each answer)

Question 12 Unsaved A sample of University of Colorado students each viewed one of two simulated news reports about a terrorist bombing against the United States by a fictitious country. One report showed the bombing attack on a military target and the other on a cultural/educational site. Additionally, before viewing the news report, each student read one of two "primes." The first was a prime for forgiveness based on the biblical saying "Love thy enemy," while the second was a retaliatory prime based on the biblical saying "An eye for an eye, and a tooth for a tooth." After viewing the news report, the students were asked to rate on a scale of 1 to 12 what the U.S. reaction should be, with the lowest score (1) corresponding to the United States sending a special ambassador to the country and the highest score (12) corresponding to an all-out nuclear attack against the country.6 (Use a diagram like Figure 9.2 from the text to display the factors and treatments.) Identify the following in this experiment:

_____ eye-for-an-eye prime

_____ the students

_____ love thy neighbor prime

_____ rating of U.S. reaction to attack

_____ prime used

_____ cultural/educational target

_____ military target

_____ type of attack

Options:

1. Subjects

2. Factors

3. Treatments for the prime

4. Treatments for the type of attack

5. Response variable

Write a complete and syntactically correct Python program to solve the following problem:
Write a program for your professor that allows him to keep a record of the students’ average grade in his class. The program must be written in accordance with the following specs:
1. The input must be interactive from the keyboard. You will take input for 12 students.

2. You will input the students’ name and an average grade. The student cannot enter an average below zero or above 100. Your program must raise and handle an exception should this occur.

   a. The exception should cause the program to return and get a new grade

3. Write all output to a file named grades.txt

4. Close the output file.

5. Open the file grades.txt for input.

6. Your program will raise and handle an exception if the file is not found.

   a. I will test this aspect by changing the file name and looking for your exception
code (your exception should cause program to ask for correct file name).

7. Read all the records from the file and display them.

Please help me to finish this code:

name,grade=input().split()
grade=int(grade)
if grade <0 or grade>100:
exceptioncheck()
def execptioncheck():
name,grade=input().split()

Question 1

One area of law which has been developing is that of the mass tort and/or class action. For example, tobacco companies won every case filed against them, year in and year out, until they finally started losing when the lawyers got together to attack the tobacco companies. There have been large numbers of lawsuits, or class actions, related to asbestos, lead, pollution (think of the movie "Erin Brockovich"), tires which failed on Ford Explorers, etc.

Assume that you are the in-charge auditor for a client company which does engineering design services for buildings, bridges, roads, port facilities, and other such items. During the year, a pedestrian walkway collapsed; the company had designed it for a stock-car racetrack in North Carolina. 20/20, the Sunday night network television program, showed some on-camera interviews in which someone made the claim that the walkway collapsed because the people who designed it had never had to solve problems 30

while they were in college; instead, all the tests they had taken were multiple-choice tests, and the result was that the people who designed the walkway did not know how to do so properly. In fact, the whole world had evidence that the design was improper, because the ten-month-old walkway had spontaneously collapsed on a clear day with little wind, when nobody was on the walkway. Thus, the designers could not credibly claim that the walkway had been subjected to stresses beyond those it was supposed to have been designed to handle.

Required:

Design an audit program for asserted and unasserted claims against this client company. Cite the authoritative professional literature related to the claims, and show how your audit program fulfills your professional responsibilities.

Martha decided to make some delicious homemade baked mac and cheese. She placed it in the oven that was really hot and when it was ready she took it out.

e) None of the above
