What is the percentage of all business students surveyed who admitted to cheating at the College?

Part A
During a study conducted, it was a lot of unethical behaviour among students. The study appears ti suggest that part of the reason for such unethical business behaviour may stem from the fact that cheating has become more prevalent among business students* (A.P.A reference insert). The article reported that 56% of business students admitted to cheating at some time during their academic career as compared to 47% of non-business students. Cheating has been a concern of the dean at the college for several years. Some members of faculty believe that cheating is not a major problem in the institute. To resolve some of these issues, the dean commissioned a study to assess the current ethical behaviour of business students at the college. As part of this study, anonymous exit survey was administered to a sample of 90 business students from this years graduating class.
Responses to the following questions were used to obtain data regarding three times of cheating.
During your time at the college, did you ever present work copied off the interet as your own? Yes or No
During your time at the college, did you ever copy answers off another students exam? Yes or No
During your time with the college, did you ever collaborate with other students on projects that were supposed to be completed individually?
Note: Any student who answered yes to one or more of these questions was considered to have been involved in some type of cheating. Use the dataset to answer the following questions to accomplish in your report below.
Assume that α = 0.05
Question 4:
Provide a classification table of college students who participated in the survey according to the following criteria:
i. All business students who copied from the internet
ii. All business students who collaborated on individual projects
iii. All business students who copied on the exam
iv. Comment on I, ii and iii.
v. All male students who copied from the internet
vi. All male students who collaborated on individual projects
vii. All male students who copied on exam
viii. Comment on v, vi and vii.
Ix. All female students who copied from the internet
x. All female students who collaborated on individual projects
xi. All female students who copied on exam
xii. Comment on ix, x and xi.
xiii. What is the percentage of all business students surveyed who admitted to cheating at the College?

Question 2: Formulate and conduct a hypothesis test to determine if the proportion of business students at the college who were involved in some type of cheating is less than that of business students at other institutes as reported by above reference in text *
Question 3:
Provide any two recommendations to the dean based on your analysis of the data?

Part B
For camera buyers, selecting a camera with many options can be a difficult process, and price is certainly a key issue for them. By spending more, will a customer really get a superior camera? Do cameras that have more megapixels a factor often considered to be a good measure of picture quality, cost more than cameras with fewer megapixels?
Working as a business analyst in an independent photography company your usual task is to analyse various digital camera data and provide results to customers which helps them make informed decisions when making camera purchases.
Your analytics team have received some dataset of some digital camera tests conducted. The data was mined from a group of photographers which tested 166 different point-and-shoot digital cameras. Based upon factors such as the number of megapixels, weight in grams, image quality and ease of use, they developed an overall score for each camera tested. The overall score ranges from 0 to 100 with higher scores indicating better overall test results.

The MS Excl file, Digital Camera dataset shows the brands, average retail price, number of megapixels, weight and overall score for 13 canon and 15 nikon subcompact cameras that were tested. Work to 4 decimal points.
Required 1a. Scatter plot – using the overall score as the dependent variable develop three scatter diagrams, one using price as the independent variable, one using the number of megapixels as the independent variable and one using weight as the independent variable.
1b. Which of the three independent variables appears to be the best predictor of overall score? Justify your answer.
2. Using simple linear regression, develop an estimated regression model that could be used to predict the overall score given the price, weight and megapixels of the camera.
Note: multiple regression ?

3. Using the observations for the canon cameras only, provide a scatterplot and regression equation of price (independent variable) against score (dependent variable)
