Question

I have een trying to figure out this problem. Facts: There is an estimated 36,000 lupus patients in Indiana. 9 of 10 patients are women. Minority women are 3 times more likely to have lupus than Caucasian women.

Problem: The total population in Lake County is 496,005 with a total of 128,163 who are Black, 82,663 Hispanic, Total minorities 218,929, total women 256,622. If there are 36,000 lupus patients, how many are women? To calculate the women do I take the total number of women and divide by 90%? For the % of lupus patients do I take 36,000 / total population of 496,005? For minority what do I calculate? Total of Black & Hispanic or total minorities figure and divide by ?? Total population?

Explanation / Answer

since 9/10 patients are women

then number of women patient = .9*36000=32400

since minorities are 3 times more likely

then number of minorities =3/4*total woman patients = 3*32400/4=24300
