Question

A study to determine haemoglobin due to the strength of medication categorised into 5 groups were conducted on 27 women aged 18-40 years. The table below displays the data and the relevant descriptive quantities. Medication strength A B C D E 0.8 0.7 1.2 1.0 0.6 0.6 0.8 1.0 0.9 0.4 0.6 0.5 0.9 0.9 0.4 0.5 0.5 1.2 1.1 0.7 0.6 1.3 0.7 0.3 0.9 0.8 0.7 a) Normality assumption was checked, and it was not normally distributed. Hence, determine if the five groups of medication strength have the same median haemoglobin level? [5 marks] b) Write a brief summary of what the result show. [2 marks]

Answer 1

The solution in details given below.

a)

solution:

We check the normality by using kolmogorv smirnov test

Ho: The data follow normal distribution

H1: The data does not follw normal distribution

p-value =0.150 and alpha value=0.05 p-value is greater than alpha value the Accept Ho

i.e The data follow normal distribution

b)

solution:
