Diploma in Information Technology Business Statistic with Python Instruction for CA3 Individual Assignment October 2020 Semester Continual Assessment 3 Individual Assignment (40%) Task: The objective of this project is for students to apply statistical concepts on real-world data and write a report on their observation. Students must ensure that their observation is supported by valid sources. This assignment will make use of what you have learnt in: • Defining and Collecting Data • Numerical Descriptive Measures • Organising and Visualising Variables • Use of Statistical Software for Data Analysis (Microsoft Excel) • Probability Distributions • Simple Linear Regression and Correlation Coefficient Read the following article on the 5G Network in Singapore: Article (1): https://www.businesstimes.com.sg/technology/imda-m1-mpa-to-conduct- coastal-5g-network-trials-with-airbus Cinquieme Generation Technology is the leading providers of Information and Communication Technology (ICT) to service providers, businesses and commercial users.

You are a consultant to Cinquieme Generation Technology’s consumers division. Your task is to understand the general trend of mobile data usage in Singapore for the last few years. You are to write a report on the current trend of mobile data usage. To ensure reproducibility, you should ensure that you include, in your report, any formula that you have used. For the following questions, download the following data sets hosted on data.gov.sg: (1) Usage of Mobile Devices for Media Activities [https://data.gov.sg/dataset/usage-of-mobile-devices-for-media-activities] (2) Total Mobile Phone Subscriptions [https://data.gov.sg/dataset/total-mobile-phone-subscriptions] (3) Mobile Data Usage [https://data.gov.sg/dataset/mobile-data-usage] Question 1 Write a report, in 750 to 1000 words, and create a spreadsheet using Microsoft Excel for the following cases. In your report, for each part of the questions, you need to describe your understandings, explain your calculations, and summarise your results. Show all your calculations in the spreadsheet, and you need to cite references to the respective worksheets in your report. Cinquieme Generation Technology has a total of 64 unmanned aircraft systems (UAS) for rent to vessels at the Singapore maritime drone estate. The booking fees for the use of UAS at the sea is $300 per day. All fees are 100% refundable if the user does not show up to claim the usage. The fixed cost (the cost that does not change with the number of UAS in used, such as radio system operating costs, etc) per day is $1000. The variable cost (the additional cost for UAS in used) per day is $150 per UAS. (i) Create a spreadsheet that calculates the total profit based on the number of rentals. What is the total profit if Cinquieme Generation Technology rented out 56 UAS? Write your answer in the report, and explain the calculation steps and formulas used, in at least 150 words. (HINT: - Create a column for total number of UAS rentals - The next column would be variable cost - The third column would be total cost - The fourth column would be revenue - The fifth column would be profit) (ii) Because of the full refund policy, it is common for user not to show up to claim the usage. Cinquieme Generation Technology is wondering if it would make financial sense to overbook and risk having not enough UAS for all users that show up to claim the usage. In that case, Cinquieme Generation Technology would find volunteers to give up their UAS in exchange for a free booking on a future date. This would cost $100 for each overbooked user. Update your spreadsheet to account for overbooked users. What is the total profit if Cinquieme Generation Technology is operating with 64 UAS after having 72 bookings for a day, assuming all 72 users show up to claim the usage? Write your answer in the report, and explain the calculation steps and formulas used, in at least 150 words. (iii) If 80 bookings are accepted, the number of users expected to show up to claim usage can be approximated by a normal distribution with a mean of 68 and standard deviation of 5. Therefore, if Cinquieme Generation Technology accepted 80 bookings for a day, what is the probability that the number of users who show up to claim the usage will result in an overbooking? Write your answer in the report, and explain the calculation steps and formulas used, in at least 150 words. (iv) Continuing with the same distribution, what is the probability that less than or equal to 60 users show up to claim the usage? Write your answer in the report, and explain the calculation steps and formulas used, in at least 150 words. (v) Comment and explain, in at least 100 words, whether Cinquieme Generation Technology should continue with their operations with full refund and overbooking strategy? Question 2 Use dataset (1), (2) and (3) to answer this question. Write a report, in 750 to 1000 words, for the following cases. In your report, describe the detailed steps on how you perform the statistical calculation. Summarise your report with your analysis findings. (i) Describe, in at least 100 words, the background of the respondents and what does each column means in the data. (ii) Describe, in at least 100 words, the types of sampling methods used, and comment on the suitability and accuracy of the sampling methods used. (iii) Describe TWO (2) survey errors that can occur in the data. Comment, in at least 100 words, on which is more significant in the data. (iv) Using appropriate measure, calculate any correlation between the media activities or age groups. Comment, in at least 100 words, on the result. (v) Create appropriate charts, and summarise the data in at least 100 words. (vi) Develop a linear regression model that can predict the usage of various media for each age group for the year 2021. Describe and comment, in at least 200 words, on the accuracy of your model. Report format 1. The report should have a cover page, content page, introduction, write-up on the task, conclusion, references and appendices 2. The cover page should include: i.
