1. Food allergy is one of the main concerns for many patients.
Insurance companies and healthcare providers are interested in the
distribution of the type of food allergyin the population. To study
AU Insurance collaborated with AU hospital and collected a random
sample of 100 patientswho have various food allergies. Each patient
provided theallergy that affects them the most. The data is saved
at file “allergy.csv”. a. (0.5points)Define the population of
interest in this study.b. (0.5 points)Define the variable of
interest in this study.c. (3points)Construct thefrequency
distribution and the frequency bar chart to describe and presentthe
distribution of food allergyin a concise manner.Attach your SPSSor
Excel outputin your report(orprovideyour R code and the output). 2.
State of Massachusetts is interested in studying the revenues
generatedby healthcare providers rangingfrom walk-in clinics to
hospitals. To conduct this study, a random sample of 196healthcare
providers were selectedand their revenues were recorded(in
$1000)for thelast year.The data is stored in
“hprevenue.csv”file.Based on these data answer the following
questions.a.(2points) Use SPSSor Excel (or R for Analytics
Students)to compute, and then reportthe summary descriptive
statistics (e.g., mean,median, mode, range,and standard deviation)
for the provider revenuesinthis sample.Explain in English what each
summary statistics mean.Attach your SPSSor Exceloutput
(orprovideyour R code and the output). b.(4points) Use SPSSor Excel
(or R for Analytics Students)toconstruct a frequency histogram of
the data set. Use the guidelines in the class notes.Start the first
interval 38below the minimum revenuevalue. Provide all the details
and explain(interval, width, etc.) on how you constructedthe
histogram. Make sure that you attach the histogram created by
SPSSor Excel(orprovide your R code and the output). c.(1
point)Comment on the shapeof the frequency distributionusing the
histogram.d.(1 point) What would be the more appropriate measure of
central tendency for these data, mean, medianor
mode?Why?e.(3points) Based on the results in part a, construct the
intervals ,2xsxsand 3xsfor the data set. Then, compare the
observedpercentage of measurements in each interval with the
percentage of measurementsyou expect to observebased onChebyshev’s
Theorem or Empirical Rule. Which rule better suits and why?Explain
usingthe histogram you generated in part b
