Answer:
 a. Odds ratio = 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
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.
