Proportion of Male and Female Students

A mobile device for the students is essential for their learning in the modern days (Norazah 2013). The mobile phone has proved to perform many functions less than the computer. The modern mobile phones have the touchscreen interface, internet access and system operations. The research studies the students demand for their smartphones in the learning systems. The paper studies students demand among the males and female students, average monthly bills, average income and the mobile brands.  

The sample technique was simple random sampling. The student’s sample of eighty was selected from the population of students from La Trobe University. The sample technique gave each student in the population the equal chances of being selected in the sample.

The data was analyzed using the descriptive statistics where measures of central tendencies were obtained. The inferential analyses were determined to show the relationships between the students earning and the choice of the phone. The preference of the phones depends ending on the discount Samsung and the iPhone.

Section A: Basic Analysis

1. b) The pie chart was used to identify the gender representation in the sample selected.

1. c) The descriptive statistics which is the pie chart was used since give a clear representation of the males and females selected in the sample.
2. Average monthly bills
3. a)  

1. b) A bar graph

1. c) The average monthly bill of the females is higher as compared to that of the males. The females being more in the sample selected their average monthly bill is higher than that of the males who are less than the females.

3. Earning and money spent on mobile phones

1. b) In the cross tabulation below the show that the males earn more than the females. Despite the fact that males are earning more than the females they spend more on average on the average money spent on bills. 

1. d) The relationship in the above indicate that their exist relationship between the average amount earned and the average amount spent on the bills.

4) Market share of mobile phone brand

1. b) Graphical representation of the graph

1. c) There exist a significant difference in the market share of the mobile in gender the males and the female. The female gender has a preference of the Apple brand and LG over the other brands. The males selected in the sample have a higher preference of the Apple brand though Samsung and other smart phones are still used.

5) Relationship between the earning student and choice of mobile phone

1. a) Average earning per brand

1. b) A graph of the average earning against the brand of the phone

1. c) Income divided in categories

1. d) A graph that represents the distribution of the phone brands across the income groups
2. e) The choice of the phone and the average income are inversely related. The income group that earns less than $2000 tends to buy more expensive phones as compared to the those earning more than $4000.

6) The effect of price on preference (Samsung versus Apple)

1. b)  Scatter plot

1. c) Interpreting the statistics below

1. d) The apple brand is more preferred as compared to the Samsung product. The customers of the Apple brand are more loyal to their brand as compared to those of the Samsung product. The preference of the Samsung brand increase with the increase of the discount offered. The higher the discount the more customers tend to buy the Samsung brand. The Apple brand despite the discount offered for their competitors still has a higher number of customers. Thus we conclude that the apple brand has more loyal customers.

The greater the percentage of the discount the more the buyers tend to go for the product. The Apple brand has more loyal customer as compared to those of the Samsung product and other products.

Section C: Advance scenarios

8. Confidence interval

1. Females 95% confidence interval

The graphical representation shows the interval in which a female will be selected in the sample using the random sampling technique.

1. Males 95% confidence interval

The graph show the interval in which a male is to be selected from the sample. The range is a probability of 0.05.

1. b)

The confidence interval show that the likelihood of selecting a male or female from the sample and being a user of a smart phone is within 100%.

9) Confidence intervals

1. b) Confidence interval for the genders

The females average earning lies $1300 and $1450 which is slightly more than that of the men

The confidence interval of the males is less as compared to that of the females. The males earn slightly less than the females.

10. Hypothesis Testing

H0: Market share is equal to 40%

H1: Market share is more than 40%

Significant level (alpha=0.01)

32.0812 And 31.9188

We reject the null hypothesis and conclude that the market share of the iPhone is more than 40% of the US market.

Significant level (alpha=0.05

31.9216 And 32.0784

We reject the null hypothesis and conclude that the market share of the iPhone is more than $0% of the US market.

Significant level (alpha =0.10)

32.0512 And 31.9487

We reject the null hypothesis and conclude that the market share of the iPhone is more than $0% of the US market.

The smartphone is one of the most used devices in modern day. The smartphone is used in home, market and the workplace. The device is used in institution for learning and communication. It is highly appreciated by both the males and the females. There is a variety of the smartphone and their preferences differ across. The iPhone is more preferred as compared to LG and Samsung.

The sampling technique is the simple random sampling. The method gives all elements in the population the chance of being in the sample selected. The simple random sampling technique is not a biased method since   the population have equal chances of being selected . the sample selected is a representation of the population and can be used to make deductions  about the population.

The sample arrived at was so small to the extent that gave a very small representation of the population. The sampling formula should be increased to ensure that it caters for higher sample to be a representation of the population.

The questionnaire was so precise leaving out the open ended question. The design of the questionnaire should be increased to cater for the general questions.

The study indicated that the iPhone is more preferred as compared to the Samsung. The higher the discounts offered for the Samsung brand the more the customers tend to buy it.
