BUS 105, trimester 2 2018 Instructions for the computing assignment worth 20% of your final grade due week 10 Preparation there are 4 things you should do before looking at the rest of these instructions. 1) Submit the drafts to section 1a,1b,1c , 1d and check the lecturer feedback 2) Skim through the sample report available from https://app.box.com/s/zmmqqj7jr0x6n5xpjnbbgawr2chwrsvv the goal of the assignment is to demonstrate you can understand and make a report that uses statistics 3) Skim through the assignment template available from https://app.box.com/s/9mjsrmazdue5znyiqqzku0kjdro2xrof This document is very similar to the assignment 4) Attempt the 5 preparation quizzes on moodle that are also due in week 10 , these will help prepare you for the assignment so you should finish them before finishing the assignment. Submission instructions *There are 7 sections you must put the answers to all sections into a single document and submit to turnitin. Note that your document must be a Microsoft Word document or pdf. If you use an Apple computer DO NOT SUBMIT A “.PAGES” DOCUMENT save it as a pdf before submitting. Links to the required materials *sample report available from https://app.box.com/s/zmmqqj7jr0x6n5xpjnbbgawr2chwrsvv * Skim through the assignment template available from https://app.box.com/s/9mjsrmazdue5znyiqqzku0kjdro2xrof *For sections 1,2,3b,5 and 6 you must use your allocated sample number available from https://app.box.com/s/g6uav7j3jwo6t82nn4kj7urma5e0ptzq *For section 1 ,2,5 and 6 you must use the following dataset https://app.box.com/s/zwoqm1t3kpdiopqw2h9m97jrvf2hlgtz *For section 3b use the dataset https://app.box.com/s/umwe110q9x0p8vh5ejpy3kppecjc6a8b The exact instructions for each of the 7 sections is given below Word limit 1500 words, Note it Is quite acceptable to have a shorter assignment if you clearly demonstrate you understand statistics and how to write a report using statistics Section 0(Cover page) “title : semester 2, 2018 bus105 computing assignment” “Name:” “Student number:” “Allocated sample:” Section 1a just considering the females make a summary of the variable “should the gym be unisex” A) Using your sample find the number of females that think the gym should be unisex and the number of females that should not be unisex B) Find the sample proportion that think the gym should be unisex and make a simple comment Section 1b Find a scatterplot show thing relationship between the variables “Time spent on weight machine” and “time spent on cardio machine” Section 1c make a summary of that lets you investigate the relationship between the variables “gender” and “should the gym be unisex” A) Use the PivotTable feature in excel to find appropriate summary statistics that let you investigate the relationship between variables “gender” and “do you want the gym to be unisex” This will probably require two PivotTables. You should paste both into word, you do not need the excel file. Make sure the pivotable (or pivot tables) include the following statistics *Just considering the females what is the sample size n1 and the proportion of people that would say “yes, the gym should be unisex” * Just considering the males what is the sample size n2 and the proportion of people that would say “yes, they think the gym should be unisex ” B) Make a simple comment about the relationship between the variables C) Using your sample what is the estimate for p1- p2? In other words what is the difference between the sample proportions - Section 1d make a summary that shows the connection between the variable gender and the time spent on cardio A) Use the pivot table feature in excel to find appropriate summary statistics for your sample. The following sample statistics must be found Just considering the females, what is the sample size n1 , the average time spent on the cardio machine , and the sample standard deviation s1 Just considering the males, what is the sample size n2 , the average time spent on the cardio machine , and the sample standard deviation s2 Paste the pivot table into the word document you do not need to submit the excel file B) Make a simple comment about the relationship between the variables using the answers to (A) C) Using your sample what is the estimate for µ1- µ2? In other words what is the difference between the sample means - Section 2 Using the information in section 1 calculate the following a) The confidence interval for the proportion of females that want a unisex gym b) The confidence interval for the proportion of males that want a unisex gym c) The test stat for testing the claim the majority of females want a unisex gym, this is the zscore of sample proportion assuming the population proportion is 0.5 d) The test stat for testing the claim the majority of males want a unisex gym, this is the zscore of sample proportion assuming the population proportion is 0.5 Section 3 a) Explain why the different main findings in the report use different methods to summarize data. b) Find an article that discusses gyms and give an appropriate summary of the dataset and state if the article agrees or disagrees with the summary. If your answer to section 3b used the same variables as the section 1 data set also provide a summary showing the relationship between to variables not used in section 1. Section 4 Use a webpage to find the p-value for the summary in section 1c, paste in a screenshot Use a webpage to find the p-value for the summary in section 1d, paste in a screenshot Section 5 Make simple conclusions based on the p-values found in section 4 Section 6 Explain the structure of a good report that uses statistics Section 7 Roughly explain the theory of Hypothesis testing. Discuss the following Are they easy to understand? Do you use a computer? type I error and type II error H0 and H1 note it is OK to explain that it is not particularly useful. SPSS tutorials do not discuss H0 and H1. If you have already done things the discussion of the plan does matter. .
