SOLUTION: Following is the frequency distribution of systolic blood pressure for smokers and nonsmokers:
Class interval nonsmokers smokers Total
90-109 10 5 15
110-129 24 15 39
130-149

Question 483268: Following is the frequency distribution of systolic blood pressure for smokers and nonsmokers:
Class interval nonsmokers smokers Total
90-109 10 5 15
110-129 24 15 39
130-149 18 10 28
150-169 9 3 12
170-189 2 2 4
190-209 0 2 2
Total 63 37 100
Suppose, A: a nonsmoker B: a smoker C: a systolic blood pressure of 170 or greater
Find
a. P(A)
b. P(B)
c. P(C)
d. P(C )
e. P(C
f. Compare d and e, and comment. Are smoking status and blood pressure level independent event?
You can put this solution on YOUR website! Following is the frequency distribution of systolic blood pressure for smokers and nonsmokers:
Class interval nonsmokers smokers Total
90-109 ::::::::::::::10 5 15
110-129 ::::::::::::::24 15 39
130-149 ::::::::::::::18 10 28
150-169 :::::::::::::::9 3 12
170-189 :::::::::::::::2 2 4
190-209 :::::::::::::::0 2 2
Total ::::::::::::::63 37 100
Suppose, A: a nonsmoker B: a smoker C: a systolic blood pressure of 170 or greater
Find
a. P(A) = 63/100
b. P(B) = 37/100
c. P(C) = 6/100
d. P(C|A) = 2/100
e. P(C|B) = 4/100
f. Compare d and e, and comment.
Are smoking status and blood pressure level independent event?
Ans: No.
