Sampling
Confidence Interval

I will start posting Mathematics (T) coursework sample answer again this term. Only sample solution for mathematical part will be posted. Thanks
Parents often wonder how tall their kids would be. Would they be short, average, or tall? Is height inherited?

1 (a) Select a random sample of 50 upper secondary students of the same gender from your school. Describe how to ensure the randomness of your sample.
(b) Record the heights of the students and their parents in centimeters.

2 Determine suitable confidence intervals for the mean height of the students using a normal distribution. Interpret your results.

The height, in cm, of a person can be predicted from one’s parents’ heights using the following formulae:
For girl: 0.5(father’s height + mother’s height) – 6.35
For boy: 0.5(father’s height + mother’s height) + 6.35
“Please ask your school teacher for introduction, methodology, and conclusion.”
3 (a) Calculate the predicted heights of the students based on of the formulae given above.
(b) Classify the predicted heights into three categories (short, average and tall).

4 (a) Carry out a suitable hypothesis test to determine whether the students’ actual heights can be modeled by the predicted heights by category.
(b) What can you say about the formula given?
(c) Comment on whether the height of a person is inherited from one’s parents.
