BRCA1 is a gene that has been linked to breast cancer. Researches at Stanford University wanted to estimate what proportion of w

omen with a family history of breast cancer show a BRCA1 mutation. In 2014, they used DNA analysis to search for BRCA mutations in 173 women with family histories of breast cancer. Of the 173, they found that 29 had BRCA1 mutations. Calculate the Point Estimate. Give your answer to 3 decimal places.

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

The inscribed angle theorem says that

m\angle CAB=\dfrac12m\angle COB

Triangle AOC is isosceles because both AO and CO are radii of the circle and have the same length. This means angles CAO and ACO have the same measure and are congruent.

Angles ACO and COD are congruent because they form an alternating interior pair between the parallel lines AC and OD.

Taking all these facts together, we have

m\angle COB=2m\angle COD

and since angle COB is made up of angles COD and DOB, these angles must be congruent, and so the arcs they subtend (CD and DB, respectively) must also congruent.
