Answer 1

Q4 aaberg c - all are the necessary components of a Rate because - Rete o> Nunesator is a part of denominator alisease seferency = No.of people infected. Rate = disease frequency anit size of population & time period duting which event I acceed 05) B A ) = (occusence = Lucicence = Rate). No. of New case of disease in a year Total population at risk " 2) D) Ratio 3- (A) Rate because time is included 4+ (B) proportion because Neumesatos is out of denominatole B (A Rate since time is involved 6) → (6) Count since no. is told X1000

WIE WIR • (b) Ratio - No of People who ate tuna salad No of people who didn't eal tunesabad 8) (B) psoption proportion since nuncratos is out of denominator I No. of sick people was ate Tuna Salad - Total no. of people who cate Tune salad TT 9→ (Atime involved so hate. 99) a 56 death off due to lung cances 100000 people = cause specific rate Total no. of people dying - due to a cause
