Before 1918, approximately 55% of the wolves in a region were male, and 45% were female. However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present approximately 65% of wolves in the region are male, and 35 % are female.. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. (Round your answers to three decimal places.) (a) Before...

Before 1918, approximately 55% of the wolves in a region were male, and 45% were female. However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present, approximately 70% of wolves in the region are male, and 30% are female. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. (Round your answers to three decimal places.) (a) Before 1918,...

In a recent survey of full-time female workers, 43% said that they would rather give up some of their salary for more personal time. Suppose you select a sample of 100 full-time female workers. A. What is the probability that in the sample, fewer than 50% would rather give up some of their salary for more personal time? B. What is the probability that in the sample, between 40% and 50% would rather give up some of their salary for...

An association surveyed office workers to learn about the anticipated usage of office computers for personal holiday shopping. Assume that the number of hours a worker spends doing holiday shopping on an office computer follows an exponential distribution. The study reported that there is a 0.58 probability that a worker uses an office computer for holiday shopping 5 hours or less. Is the mean time spent using an office computer for holiday shopping closest to 5.8, 6.2, 6.6, or 7.0...

The Economic Policy Institute periodically issues reports on wages of entry level workers. The institute reported that entry level wages for male college graduates were $21.68 per hour and for female college graduates were $18.80 per hour in 2011 (Economic Policy Institute website, March 30, 2012). Assume the standard deviation for male graduates is $2.30, and for female graduates it is $2.05. a. What is the probability that a sample of 50 male graduates will provide a sample mean within...

Question 55: Please refer the scenario below for questions 55-56: All workers at one of Cannondale's factories completed a survey that asked if they were willing to ride a bicycle to work, should Cannondale provide them one for free. Of the 96 workers that lived less than five miles away, one third said they would. Of the 48 that lived between 5 and 10 miles away, 25% said they would. Of the 25 that lived between 10 and 15 miles...
