while others have not. However‚ a more controversial issue is the explicit relationship between unemployment and crime. In other words‚ does unemployment cause crime or are there other causes (Papps and Winkelmann)? Specifically‚ does the average median income of a household‚ the individual poverty level‚ high school graduation rate‚ population‚ or the rate of divorce have influences on crime in the US?

2. Find a 95% confidence interval for the proportion of all acceptable students with a combined score less than the median(356) who choose Harrigan’s rival over Harrigan. Do the same for those with a combined score greater than the median. “less than median” = 26/75 = 0.3467 = sample mean 95% confidence interval = 0.3467 ± 1.96*0.5/(75)^0.5 = 23.35%~45.98% “greater than median” = 48/75 = 0.64 = sample mean 95% confidence interval = 0.64 ± 1.96*0.5/(75)^0.5 = 52.68%~75.32% 4. a) 95% confidence

This rapid growth can be traced back to Milton Rock and Edward Hay who brought about “peer groups” as a means of evaluating executive compensation. These peer groups essentially rigged the compensation system where all CEO’s are seen to be above the median‚ therefor their pay increases continuously (Elson and Ferrere‚ 2013). Attacks on this excessive executive pay

by your total number of value (12) you get 83.17 average test scores this is your mean. The median‚ or middle value‚ is the center of an ordered list of numbers. So you would have half of the values on one side and half on the other. The median is the middle value. When using the mean as a measurement‚ extreme values can have a major effect on the mean outcome‚ in which case researchers are likely to median
