1) The U.S. Bureau of Labor statistics conducte periodic surveys to collect information on the labor market. According to a recent survey, hourly workers in the private sector in a particular metropolitan area earn an average of $11.75 per hour, with a standard deviation of $2.10 per hour The pattern of these sample results suggests that "hourly private sector wages follows a normal distribution for this metro area. Based on this information: a) what percentage of workers in this area...

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...
