[2 marks]ii Suppose that you are interested to know reading and watching financial behaviour of two other groups of people: those who are below age 55 and those who are 55 and above. Using an appropriate graph, present and discuss variation in reading/ watching financial news behaviour of these two age groups.[2 marks]iii Do we have sufficient evidence to infer that more people watch financial news compared to read them? [3 marks]iv Is there sufficient evidence to infer that men read financial section of the newspaper more than women? Use p-value approach. [4 marks]v Using an appropriate statistical test, infer if there is a statistical difference in reading financial section of the newspaper among two age groups (55 and older and below 55).[4 marks]QM2 Assignment 1 Summer 2016 Page 3Question 2: Success behind a Growth Mindset (15 Marks)In her ground-breaking research, Carol Dweck, a world-renowned psychologist from Stanford University, found that success is accorded to an individual based on whether they have a growth mindset or a fixed mindset. It is believed that those with a Growth Mindset can develop their abilities through dedication and hard work, while on the contrary, the abilities of those with a Fixed Mindset can only remain at a constant level.A great believer of the Growth Mindset, a high school principal, decides to investigate the difference in performance of his Year 12 students based on their mindset. He first chooses a group of Year 12 students and presents them with a questionnaire, allowing them to identify if they are either an individual with a Fixed or Growth Mindset. He then divides the students into two groups based on the two respective Mindsets and collects their past Year 11 test results.Given below are the average test scores for three subjects (Maths, English and Physics) for three terms tests and their standard deviations.Average marks for 3 term tests (standard deviations in parenthesis)GroupNumber of studentsMathsEnglishPhysicsAverage marks for all 3 subjectsGroup 1: Fixed Mindset10063 (11.3)73 (10.9)68 (11.1)68 (11.1)Group 2: Growth Mindset15086 (7.5)82 (7.1)91 (7.2)86 (7.27)After looking at the data collected, the principal placed his Year 12 students in a series of training sessions to highlight the importance of Growth Mindset. He then ran another survey at the end of the year for the students he had categorised under ‘Fixed Mindset’ and collected their test marks for the same subjects in Year 12. These statistics are given below.Average marks for 3 term tests (standard deviations in parenthesis)GroupNumber of studentsMathsEnglishPhysicsAverage marks for all 3 subjectsGroup 1: Fixed Mindset10081 (9.1)83 (8.9)88 (8.8)84 (9.21)Note: Assume that these samples are drawn from normally distributed populations, which have equal variances. You may use EViews to complete this question.QM2 Assignment 1 Summer 2016 Page 4i Using relevant data, infer that the average marks in the three subjects (Maths, English and Physics) are statistically different for each group.[4 marks]ii Perform a statistical inference to determine if students with Growth Mindset perform better than those who have a Fixed Mindset, on average (again, only use most relevant data).[4 marks]iii Is there any statistical evidence suggesting that the series of training sessions were successful (and hence the performance of those with Fixed Mindset improved)?[3 marks]iv Briefly explain the difference between the tests you performed in parts i, ii and iii above.[2 marks]v Briefly explain why parametric tests are preferred to non-parametric tests, as well as, when and why non-parametric tests are performed instead of parametric tests.[2 marks]END OF ASSIGNMENT
