Question

Using 0.05 level of significance and assuming that the data is normally distributed: • Tell whether there is a significant difference in the mean systolic pressure of respondents before and after the treatment.

VARIABLES:
a) "Exercise" = 0 stands for 'no' & 1 stands for 'yes'
b) "Serum cholesterol" = provided in mg/dL
c) "Weight" = provided in pounds
d) “Smoking status"
• 0 stands for 'does not smoke'
• 1 stands for 'smoke less than one pack per day'
• 2 stands for 'smoke one or more than one pack per day'
The given information below shows the result of health exam taken from 100 randomly
selected individuals who undergoes treatment for their high blood.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
