In an experiment to study the relationship to studyhypertension and smoking habits, the following data are collectedfor 180 individuals:

Nonsmokers modsmokers Heavysmokers
H 21 36 30
NH 48 26 19

Where H and NH in a table stand for hypertension andnonhypertension, respectively. If one of these individuals is isselected at random, find the probability that the person

(a) experiencing hypertension, given that the person is a heavy smoker
(b) a nonsmoker given that the person is experiencing no hypertension.

a) 0.612, b) 0.52.

Step-by-step explanation:

Since we have given that

              Nonsmokers  mod smokers Heavy smokers  Total

H                   21              36                         30                 87

NH                48              26                         19                93

Total              69             62                          49               180

Here, H stands for Hypertension

NH stands for Non hypertension

(a) experiencing hypertension, given that the person is a heavy smoker

P(H|Heavy smoker) =

(b) a nonsmoker given that the person is experiencing no hypertension.

P(Non smoker | No Hypertension) =

Hence, a) 0.612, b) 0.52.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it
