A gender-selection technique is designed to increase the likelihood that a baby will be a girl. In the results of the gender-selection technique, 856 births consisted of 438 baby girls and 418 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 438 girls in 856 births. b. Find the probability of getting 438 or more girls in 856 births. If boys and girls are equally likely, is 438 girls in 856 births unusually high? c. Which probability is relevant for trying to determine whether the technique is effective: the result from part (a) or the result from part (b)? d. Based on the results, does it appear that the gender-selection technique is effective? a. The probability of getting exactly 438 girls in 856 births is 0.0216 . (Round to four decimal places as needed.) b. The probability of getting 438 or more girls in 856 births is (Round to four decimal places as needed.)

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 93 people in the 18-21 age bracket and finds that 79 of them respond and 14 refuse to respond. When 266 people in the 22-29 age bracket are contacted, 237 respond and 29 refuse to respond. Assume that 1 of the 359 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond. Report the answer as a percent rounded to one decimal place accuracy.
