Answer: B= A/(C+D)
Step-by-step explanation:
A = B(C+D)
Divide each side by B
A/B= C+D
Reciprocate both sides
B/A = 1/(C+D)
Now multiply each side by A
B = A/(C+D)
Answer:
The point estimate for the proportion of women with BRCA1 mutation is 0.168
Step-by-step explanation:
The point estimate for the proportion of women with BRCA1 mutation is the number of women with this mutation divided by the size of the sample.
Of the 173, they found that 29 had BRCA1 mutations.
29/173 = 0.168
The point estimate for the proportion of women with BRCA1 mutation is 0.168
