Classmate 1
The major event or scandal during the global recession of 2008 and 2009 was complaints of unethical behaviors by Wall Street executives, financial managers, and other corporate officers. During the scandal, an article in Chronicle of Higher Education surfaced suggesting the action behind the unethical practices. Additionally, it stated that part of the action behind the unethical business behavior is the frequent cheating caused by business students. A total of 56% of business students confessed to cheating at a point in their academic year, while 47% were non-business students, as reported by the article. The Dean of the College of Business at Bayview University was concerned on how to eradicate cheating from his institution for several years. A few staff of Bayview University believe that cheating is high at the institution compared to other universities, while the other set of staff members think cheating is not the issue with the university. The dean decided to keep the peace among the faculty members by conducting a survey to assess the current ethical behavior of business students at Bayview. He surveyed 90 graduating business students. The result represented three types of cheating.
Solution:
The following is the 95% confidence intervals for the proportion of students that were involved in some type of cheating.
All the business students:
P=.4111
Margin of error = z.025√ (p (1-p)/n = 1.96 √. 4111(1-.4111/90 =.1017
95% confidence interval = .4111 ± .1017 or .3094 to .5128
Male students
p= .4375
Margin of error = z.025√ (p (1-p)/n = 1.96 √. 4375(1-.4375/48 =.1403
95% confidence interval = .4375 ± .1403 or .2972 to .5778
Female students
p= .3810
Margin of error = z.025√ (p (1-p)/n = 1.96 √. 3810(1-.3810/42 =.1469
95% confidence interval = .3810 ± .1469 or .2341 to .5279
The analysis showed that Bayview University has a high rate of cheating among its business students, and adequate precautions needs to be taken to control the wide spread of heating.
Classmate 2
Cheating entails deception and trickery and goes against morals and affects business practices. Example includes militants, who do so to pass a certain type of message. (Marian 2020), “Most business ethics scholars consider that the very idea of cheating is indefensible on moral grounds” (p.1). This violates rules and brings about punishment in business and other area of life. We can see that from the readings in the class text, 36% of student has done any type of cheating (29% are female and 42% are male). 18% has copied form internet and 20% copied on exam.
Proportion of all students involved in any type of cheating (pa) = 0.3556
Critical Z at 95% confidence interval= 1.96
For Males,sample proportion, pcap = 0.4375sample size, n = 48Standard error, SE = sqrt (pcap * (1 – pcap)/n)SE = sqrt (0.4375 * (1 – 0.4375)/48) = 0.0716
Given CI level is 95%, hence α = 1 – 0.95 = 0.05α/2 = 0.05/2 = 0.025, ZC = Z(α/2) = 1.96
CI = (pcap – z*SE, pcap + z*SE)CI = (0.4375 – 1.96 * 0.0716, 0.4375 + 1.96 * 0.0716)CI = (0.2972, 0.5778)
For Females,sample proportion, pcap = 0.3809sample size, n = 42Standard error, SE = sqrt (pcap * (1 – pcap)/n)SE = sqrt (0.3809 * (1 – 0.3809)/42) = 0.0749
Given CI level is 95%, hence α = 1 – 0.95 = 0.05α/2 = 0.05/2 = 0.025, ZC = Z(α/2) = 1.96
CI = (pcap – z*SE, pcap + z*SE)CI = (0.3809 – 1.96 * 0.0749, 0.3809 + 1.96 * 0.0749)CI = (0.2341, 0.5277)
