Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 94 people in the 18-21 age bracket and finds that 80 of them respond and 14 refuse to respond. When 265 people in the 22-29 age bracket are contacted, 241 respond and 24 refuse to respond. Assume that 1 of the 359 people is randomly splected. Find the probability of getting someone in the 22-29 age bracket or someone who refused to respond. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. P(22-29 or refused) = (Hint: It might be helpful to organize the data into a table first.) Question Help: B Written Example Message instructor

A recent study shows that 4% of California residents consider purchasing an electric car . If we randomly choose 10 residents, what’s the probability that 2 of them consider purchasing an electric car?

A survey showed that 71​% of adults need correction​ (eyeglasses, contacts,​ surgery, etc.) for their eyesight. If 8 adults are randomly​ selected, find the probability that at least 7 of them need correction for their eyesight. Is 7 a significantly high number of adults requiring eyesight​ correction?

Suppose that 40% of Tulane undergraduates intend to continue on to graduate school after completing their undergraduate degrees. Suppose we randomly select 20 Tulane undergraduates. Find the probability that at least 11 of the students in the sample intend to continue on to graduate school.

Suppose that 20% of fruit flies possess a certain gene.  If we randomly select 20 fruit flies, find the probability that at least 5 flies in the sample possess the gene.  You may assume sampling with replacement.

Suppose that 20% of fruit flies possess a certain gene.  If we randomly select 20 fruit flies, find the probability that at least 7 flies in the sample possess the gene.  You may assume sampling with replacement.

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 102 people in the 18-21 age bracket and finds that 87 of them respond and 15 refuse to respond. When 249 people in the 22-29 age bracket are contacted, 220 respond and 29 refuse to respond. Assume that 1 of the 351 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who responds. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol.
