Would you please show how you would solve PSAT test section 4, #16? Thank!s
Sure! First, figure out how likely it is that a 14 or 15 year old would not have a summer job. 69 out of 89 kids ages 14-15 do not have a summer job. is approximately 0.78.
Now figure out the likelihood of a 16 or 17 year old not having a summer job. 42 out of 81 kids ages 16-17 do not have a summer job. is approximately 0.52.
How many times more likely is a 14-15 year old than a 16-17 year old NOT to have a summer job? . That’s answer choice C.
(If you don’t round in the intermediate steps, the answer still rounds neatly to 1.50: , which rounds to 1.50.)
