Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 99 people

sertanlavr [38]

Answer:

The probability of getting someone in the 18-21 age bracket or someone who agreed to respond $= 0.365$

Step-by-step explanation:

The counts are as follows

Age Group No of people contacted No of refusals Total

18-21 88 8 96

22-29 240 42 282

Total 328 50 378

The probability of getting some one in the age bracket of 18-21 or some one who refused to respond is

$= \frac{96}{378} + \frac{50}{378} - \frac{8}{378} \\= \frac{96+50-8}{378} \\= \frac{138}{378} \\= 0.365$
