Introduction The objective of this report is to highlight the mobile phone choice exhibited by students at the La Trobe University and the relation of this choice with different factors such as gender, earnings and underlying discount available. The data used for this research has been derived using random sampling from the population data comprising of the survey results of the various students studying at La Trobe University. The sample size selected for this study is 175 and considering the sample size and random sampling, it is expected that the sample obtained would be representative of the underlying population of interest. Data Analysis Section A: Basic Analysis 1.The numerical summary and graphical representation of gender proportions. Numerical summary: Pivot table Graphical representation: Pie chart 1

Considering the dismal value of coefficient of determination, it may be concluded that the relationship between earnings and money spent is not related for either of the genders (Hillier, 2016). 4
(4) The numerical summary to represent the market share of each mobile brand by gender is shown below: Relative frequency table Section B (5) The average earning of students and their mobile phone choices are represented in the form of pivot table shown below: 5
From the above, it seems that the earnings and mobile choice is related considering the deviation in average earnings of the respective phone users. For instance, average earnings of LG mobile users are almost half that of Apple mobile users which is quite significant and cannot be ignored. 6

It is apparent that there seems to be difference in the mobile choice in the different earning groups. For high income earners, it is apparent that only Apple and Samsung are the two choices which are considered as premium brands. LG is only concentrated with the low income group. Hence, it is evident that choice of mobile phone does seem to be different amongst the different earning groups. (6) The requisite results obtained are highlighted below. 7

Considering the above results and also the high coefficient of determination, it is apparent that as the discount on Samsung Galaxy phone tends to increase more proportion of users would tend to make a switch towards Samsung from iPhone (Flick, 2015). (7) The requisite output is shown below. 9

It is apparent that males seem to be more receptive to the discount in comparison to females. This is apparent from the higher slope coefficient of males in comparison with females. This highlights that there is a difference in the gender with regards to response to the discount (Hair et. al., 2015). Section C (8) The requisite computation is shown below. 10
95% confidence interval 11
With 95% confidence, we can state that population proportion of selected individual being male would lie between 0.453 and 0.528. Also, with 95% confidence, we can state that population proportion of selected individual being male would lie between 0.476 and 0.552 (Eriksson and Kovalainen, 2015). (b) Number of students who will use mobile phones is shown below: Sample proportion (students are using smart phone) = 678/679 = 0.9985 12

From the above output, we can conclude with 95% confidence that the population proportion using a mobile phone would lie between 0.9947 and 1.0000 (Flick, 2015). (9) The requisite computation is shown below. 13
With a 95% confidence, it can be stated that average earnings of the male population would lie between $ 1,126.21 and $1,334.84. Further, with 95% confidence, it can be states that average earnings of the female population would lie between $ 1,152.41 and $ 1.369.41 (Hillier, 2016). (10)Hypothesis testing Step1 Hypotheses H0:pβ€0.40 14
Ha:p>0.40 Step 2 Test statistics Proportion of iPhone users = 138/175 = 0.7886 Now, Standard deviation =β0.7886(1β0.7886) 175=0.03086 The z valuez=0.4β0.7886 0.03086=β12.5889 Step 3 The p value corresponding to z value comes out to be 0.00. Step 4 Level of significance = 1%, 5%, 10% Step 5 It can be seen from the above that p value is lower than all the levels of significance and therefore, sufficient evidence is present to reject the null hypothesis and to accept the alternative hypothesis (Hair et. al., 2015). Therefore, the claim that market share of iPhone is higher than 40% is correct. 15

Summary and Discussion On the basis of the above analysis, it may be concluded that the choice of mobile phone is significantly influenced by the earnings as high income earners do not use any phone except Samsung Galaxy and Apple iPhone. Also, there is significant different between the gender based trend related to spending on money and also the earnings level. However, no significant relationship has been found between earnings and money spent for either of the genders. Further, it is also seen that as a higher discount is given by Samsung Galaxy, a larger proportion of students tend to make a shift from Apple iPhone. This trend is more prevalent amongst the males. Further, it has also been found that iPhone share is more than 40% for La Trobe university students as well. 16
