# BLO1001 Business Statistics Report, SUSS, Singapore: Body mass index (BMI)[1] is a person’s weight in kilograms divided by the square of height in meters

Question 1

Body mass index (BMI)[1] is a person’s weight in kilograms divided by the square of height in meters. BMI is an inexpensive and easy screening method for categorizing weight measurement, be it underweight, healthy weight, overweight, or obesity.

Using the random sampling method, describe how you would select 10 students from EACH diploma course to form a new sample dataset of 60 students. Based on this sample dataset, determine the mean BMI and construct a 95% confidence interval for the population mean. Comment on this 95% confidence interval as compared with the healthy adult’s BMI (18.5 to 24.9) (published by MOH)[2]. Explain what the impact is if you increase the confidence level from 95% to 99%.

Question 2

Dr Jim Tan, a health consultant at MOH, published a research article about obesity issues recently. He believed that the BMI for Singaporean adults is normally distributed with a population mean of 21.

Based on your sample dataset (consists of 60 students) used in Question 1, can you conclude that the sample mean BMI is different as compared to the population mean at 0.05 level of significance? Use p-value approach to perform your hypothesis testing. What can you conclude if the level of significance is changed from 0.05 to 0.01?

Question 3

Reference to Question 2, Dr Jim Tan in his research article on the obesity issues commented that the consumption of soft drinks/bubble tea is correlated to the BMI. He also linked the consumption level to the lifestyle (including type of diploma courses for full-time students, work/family related stress, weekly physical exercises, etc.) of a person.

Based on the complete RDC Excel file (consists of 975 students), can you conclude that there is a difference among the students of the six diploma courses in terms of the consumption level of soft drinks/bubble tea? Use p-value approach to perform your Chi-square goodness-of-fit test at 0.05 level of significance. Do you agree with Dr Jim Tan concerning the students in different diploma courses evidenced in different consumption level of soft drinks/bubble tea?

1.What are the key takeaways that you find them useful and why?

2. How can you learn better if you can restart your learning journey?

3. Provide an example of business related scenario where hypothesis testing (or Chi-square goodness-of-fit test) can be used to gain insight and for better decision-making. Explain how the required raw data can be collected and analysed.
