A small city has two hospitals, General and County. Cityadministrators compiled the following data set, pertainingto heart attack survival rates, over a 5 year period:Survival StatusHospital Survived Died TotalGeneralCountyTotal1. Fill in the above table and the blanks below to show howto compute the following:Pr(Survived | General) =Pr(Survived County) =The administrators at General Hospital felt that thestatistics presented in the above table gave a falseimpression of the relative quality of care at the twohospitals. They stratified the data set above according to"Heart Attack Severity Level" (Moderate vs. High):HighModerate Survival StatusSurvival StatusHospital Survived Died Total Hospital Survived Died TotalGeneral 232 123355 Kieneral131 250 381012 034 046County 129 089 218 CountyTotal 361 212 573 Total143 284 427Pr(Survived County, Moderate) =.5922.

he level of cretaine phosphokinase (CPK) in blood samples measures the amount of muscle damage for athletes. At Jock State University, the level of CPK was determined for each of 25 football players and 15 soccer players before and after practice. The two groups of athletes are trained independently. The data summary is as follows : For football players: Data for Football players n=25 Before Practice After Practice Difference (Before-After) Mean 254.73 225.6 29.13 Standard deviation 115.5 132.6 21.00 For soccer players: Data for Soccer players n=15 Before Practice After Practice Difference (Before-After) Mean 177.1 173.8 3.3 Standard deviation 60.7 64.4 6.88 Assume that all the data above are normal Test the claim that the mean CPK level has DECREASED for soccer players AFTER exercise (compared to the mean BEFORE exercise), using α=0.10. AFTER practice, do football players have a DIFFERENT mean CPK values compared to soccer players? Test this claim by…
In this unit, you looked at numerical measures for statistics, including measures of central tendency and distribution for one-dimensional data and correlations for two-dimensional data. You also used histograms, box plots, and scatter grams to visually analyze central tendency, distribution, and correlation. What do you consider to be the advantages of the numerical values? What do you consider to be the advantages of the visual representations? Which do you prefer working with, and why?
A County Board of Supervisors has appointed an urban planning committee to evaluate proposed community development projects. The committee is analyzing, among other things, data on household incomes in two cities within the county. They have collected data on the income of 80 households in each of the two cities. The histograms below show the distributions of the two sets of incomes (in thousands of dollars). Each histogram shows household income on the horizontal axis and number of households on the vertical axis. The means and standard deviations for the data sets are also given.
