Question

For the population of women whose mothers took the drug DES during pregnancy, a sample of 3980 women showed that 63 developed tissue abnormalities that might lead to cancer. Provide a descriptive statistic (to 1 decimal) that could be used to estimate the number of women out of 1,000 in this population who have tissue abnormalities.

Answer 1

Answer: 15.8 Women out of 1,000 have tissue abnormalities.

Explanation:

It's pretty simple, all you need to do is set up a proportion with the variables you already have

63/3980 = x/1000

Do Cross products so

63000=3980x

Divide both sides by 3980 to get x by itself and you get 15.82914573 which reduced to 1 decimal is 15.8

Answer 2

Answer is 16

Explanation:

Given that for the population of women whose mothers took the drug DES during pregnancy, a sample of 3980 women showed that 63 developed tissue abnormalities that might lead to cancer.

From the given information, we find the proportion of women who took the drug and developed tissue abnormalities

Proportion p =
`(63)/(3980) =0.015829`

Assuming the same proportion continues constantly for any population, we find

the number of women out of 1,000 in this population who have tissue abnormalities, estimated =
`1000(0.015829)\\=15.829\\=16`
