EGD207: Hypothesis Testing on Population Mean, Assignment 2, NYP, Singapore, Singapore

PART 1:  Hypothesis Testing of Mobile Data Usage by NYP Students

To conduct a statistical analysis to investigate the claim that NYP students consume more than the average mobile data usage per month in Singapore by employing hypothesis testing of one population mean. This will involve the following steps:

Step 1: Find the average monthly mobile usage per subscriber in Singapore   

Step 2: Construct the hypotheses and find the critical values

Explain the meaning of a type 1 error in this hypothesis and its relation to α:

Step 3: Computing the sample data and the test statistics  

You need to collect data from at least 20 schoolmates on their actual mobile data usage in the recent months and to complete the table below:

Assumptions for using z – test or t – test:

Step 4: Making decision and conclusion

Reflection: State 3 learning points.

PART 2: Market a Customised Mobile Plan to Polytechnic Students

As part of your internship at a particular telco company, you are required to customise and market a SIM-only mobile plan to our polytechnic students – the Generation Z.

Your marketing research will involve the following:

• the average monthly mobile data usage by NYP students (from Part 1);
• the expected monthly cost that our students are willing to pay;
• the current mobile plans available in the market;
• any other useful information to customise a SIM-only mobile plan for our students.

Step 1: Frequency Table & its Probability Distribution

Expected monthly cost =

Step 2: Current SIM-only mobile plans available in the market

Step 3: Any other useful information

Step 4: Write up of the customised mobile plan for our students and justify your plan
