STAT Capella University Normal and Standard Distribution Practice Questions Capella University, Mathematics STAT Capella University Normal and Standard Distribution Practice Questions Question Description You are asked to conduct a study of shelters for women who have experienced domestic violence in order to determine the necessary capacity in your city to provide housing for most of these women. After recording data for a whole year, you find that the mean number of women in shelters each night is 250, with a standard deviation of 75. Fortunately, the distribution of the number of women in shelters each night is normal, so you can answer the following questions posed by the city council. Question 1 2 PointsIf the citys shelters have a capacity of 350, will that be enough places for abused women on 95% of all nights? Yes No Question 2 2 PointsWhat number of shelter openings will be needed? 250 370 75 374 Question 3 2 PointsThe current capacity is only 220 openings because some of the shelters have been closed. What is the percentage of nights that the number of abused women seeking shelter will exceed current capacity? 62.21% 65.54% 34.46% 40% A criminologist developed a test to measure recidivism, where low scores indicated a lower probability of repeating the undesirable behavior. The test is normed so that it has a mean of 140 and a standard deviation of 40. Question 4 2 PointsWhat is the percentile rank of a score of 172? 78.81st percentile 80th percentile 40th percentile 28.81th percentile Question 5 2 PointsWhat is the z-score for a test score of 200? -1.50 0.5 1 1.50 Question 6 2 PointsWhat percentage of scores falls between 100 and 160? 28.81% 53.28% 19.15% 34.13% Question 7 2 PointsWhat proportion of respondents should score above 190? 0.5 1 1.50 1.25 Question 8 1.5 PointsSuppose an individual is in the 67th percentile in this test. What is his or her corresponding recidivism score? 155.9 140 157.6 112.9 According to National Collegiate Athletic Association (NCAA) data, the means and standard deviations of eligibility and retention rates (based on a 1,000-point scale) for the 20132014 academic year are presented, along with the fictional scores for two basketball teams, A and B. Assume that rates are normally distributed.Normal Distribution Practice data Question 9 1.5 PointsOn which criterion (eligibility or retention) did Team A do better than Team B? Calculate appropriate statistics to answer this question. Team A has better retention and eligibility than Team B. Team B has better retention and eligibility than Team A. Team B has better retention but Team A has better eligibility. Team A has better retention but Team B has better eligibility. Question 10 1.5 PointsWhat proportion of the teams have retention rates below Team B? 43.25 4.325 0.4325 0.04325 Question 11 1.5 PointsWhat is the percentile rank of Team As eligibility rate? 43.25th percentile 36.54th percentile 35.94th percentile 17th percentile "Place your order now for a similar assignment and have exceptional work written by our team of experts, guaranteeing you "A" results."
