a) Calculate the sample standard deviation.

b) Calculate the first, second and third quartiles, and interpret each result.

c) What scale of measurement can be applied on the weight variable?

3) The mean weight (kg) and its associated standard deviation (kg) among hypertensive patients were 68kg and 10kg respectively. Also, the mean height (cm) and its associated standard deviation (cm) were 158cm and 8cm respectively. Compare the variability between the two measurements and interpret the results.
