Researchers gathered data from various hospitals to determine if the success rate of heart
transplants differed based on the volume of transplants done at the hospitals. The
following grouped boxplot shows mortality rate (deaths per year per 100 patients) for heart
transplant patients at a sample of hospitals categorized as either low-volume or high-
volume
Sol:
mortality rates is greater in low volume hospitals as median=28 as compared to
mortality rates in high volume hospitals which is median=18
No outliers seen in low volume hospitals and high volume hospitals.
high volume hospitals is approximately follows normal distribution compared to low volume hospitals which follow skewed distribution.(positively skewed)
Inter quartile range(IQR) for low volume hospitals=Q3-Q1=32-16=16
Inter quartile range for high volume hospitals=Q3-Q1=20-12=8
IQR is high for low volume hospitals compared to high volume hospitals
Range for low volume hospitals=max-min=32-2=30
Range for high volume hospitals=26-8=18
From boxplot we can conclude that there are differences in
mortality rates (deaths per year per 100 patients) for heart
transplant patients at a sample of hospitals categorized as either low-volume or high-
volume.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
