{40-59, 5826 ,123, 0.2 ,22.90}
{ 60+ 6419, 136, 0.5, 40.06}
the data was collected on 19,921
Assuming that the populations these samples are drawn from are normally distributed, which seems reasonable given the figures in the paper,
1) what are the median and mode for each age-group population?.
2)Hypertension is diagnosed when a person’s systolic blood pressure is greater than 140 mm Hg. To find the proportion of individuals in each population who have hypertension, we need to convert 140 to a z-score.
a)Which formula from the chapter would be appropriate?
b)Would the standard deviation or standard error be used?.
3) Without doing any calculation, how will the proportion that would be diagnosed as hypertensive be different for each age group population?
a)Which age group will have the largest proportion that is hypertensive?
b)Which age group will have the smallest proportion that is hypertensive?
Find the proportion of each population that has hypertension:
a)What proportion of the population aged 18-39 has hypertension?
b)What proportion of the population aged 40-59 has hypertension?
c)What proportion of the population aged 60 and over has hypertension?
What does the larger variability for the oldest age group suggest about the health of the population?

The pain radiates toward her hip and down the back of her leg and goes away with rest. She reports having these symptoms for at least six months, but now it seems as though she is able to walk less and less before the pain sets in.
