dents is 8:1. The international students composed of students from Asia and parts of Europe.

Price and average quantity consumed

From the data, it is clear that the price of the drinks has a negative relationship to the quantity demanded. Increase in price leads to a decrease in the total intake of drinks as per the students in the survey. This indicates that as much as beverages are important for the students, there are other items which are important and increase in price of the beverages may make the student be less inclined to purchase he beverages. The table below shows a sum total of the units of beverages which would be purchased by the students in case they experienced an increase in price which shows a general decline in consumption.

Serial no.	Price	Total Intake by 90 Students
1.	$0.50	988
2.	$1.00	829
3.	$1.50	700
4.	$2.00	532
5.	$2.50	426
6.	$3.00	323
7.	$3.50	268
8.	$4.00	162
9.	$4.50	127
10.	$5.00	83

Popular & least popular soft drinks

From the data, it is clear that the popular drinks among the student seem to be more inclined to drinking energy drinks and soft drinks compared to water and milk drinks. This is clear since from the survey when they were asked about which beverages they would prefer above other drinks they selected energy drinks more than all the other drinks (Chatfield, 2018). This could indicate that since the students require energy for sports activities, they would require energy drinks for their activities. Also, the might require energy drinks in order to study well at night. The students may not prefer water since it is part of their day to day lives and therefore they might not be strongly inclined to their consumption (Chambers, 2017).

Loyalty vs Discount

In terms of loyalty to brand, it is clear that the students will be loyal to their preferred brand in the case they receive a 25% discount but may shift preferences in case they receive a higher discount of 40% discount. For instance, 24 students out of 87 students said that they will change their preferences while 63 students said that they would not change their preferences. When the discount changed from 25% to 40%, 52 of the students said that they would change their preferences. To sum, the level of student loyalty is affected by the amount of discount that the students expect.

Demand of International Students 

From the study it is clear that the demand of the international students and that of the local students is more or less similar. There is a decrease in consumption with an increase in price. This shows that both the local and international students are both influenced by similar factors which affect the demand of the products in relation to a price increase (Cox, 2018).

International students

$0.50	$1.00	$1.50	$2.00	$2.50	$3.00	$3.50	$4.00	$4.50	$5.00
76	75	56	34	24	27	33	20	22	22

Local students

$0.50	$1.00	$1.50	$2.00	$2.50	$3.00	$3.50	$4.00	$4.50	$5.00

Most and least popular drinks among local students and international students

	Soft drinks	Fruit Juice	Tea /coffee	Energy drinks	Other (water, milk drinks etc.)
International	36	30	24	43	17
Local	239	217	224	314	161

From the data, it is clear that both the international and local students prefer energy drinks compared to other drinks. However, the soft drinks also come in second as a popular drink among the students.

Probability of choosing soft drink as first choice

 15 students will choose soft drink as their first choice. 15/87

A proportion of 17%

Confidence interval = p +/- Z* Squareroot (p(1-P) /n

Z value = 1.96

1.96* Squareroot (17%*83%/87)

= +/- 8%

Confidence interval = 9%, 25%

Summary

This analysis contained results from

No. of local Students	No. of International Students
77	10

From the data it is clear that there is a close correlation between the preferences of the international students and the local students in terms of beverage popularity

Overall, the preferences of the general student population which was surveyed in the study is a representation of the trends and preferences of both the local and international students. All students react in the same way when it comes to increase in prices and the quantity demanded. In addition, all students prefer energy drinks to health drinks. Also, the students are loyal to the drinks they prefer only to the extent that the drinks have a min of 25% discount but if the discount is more, the students may shift their preferences. This study has managed to provide a comprehensive view of student preferences in terms of drink consumption given their nature of being both local and international students (Silverman, 2018).
