b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning

Explanation:

For case study

Let 'a' represent the total population of people with melanomia = 696

Let 'b' represent the total number of people with melanomia exposed to indoor tanning = 1107 – 696 = 411 people

For control study

Let 'c' represent the total population = 1500

Let 'd' represent the total number of people not exposed to indoor tanning = 1500 - (0.428 * 1500)

= 1500 - 723

Total number of people not exposed to indoor tanning = 777 people

a. Odds ratio = (a/b) / (d/c) = (696/411) / (777/723)

= 1.69 / 1.07 = 1.58

b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning.
