STS 345: Statistics for Health Sciences Assignment # 2
In this assignment, you will explore and apply the concepts of frequencies, percentages and percentiles, normality, probability, central tendency, and dispersion. Using the dataset provided, complete each of the following questions and run the appropriate Excel or JASP commands that follow. Please answer each of the questions below in red font. Part I. Frequencies, Percentages and Percentiles 1.
A researcher is interested in knowing whether the frequency of COVID-19 cases are disproportionally burdened in certain races/ethnicities. Using the data provided below, please create a frequency distribution table to show the number of COVID-19 cases for each race/ethnicity. (See Frequencies and Percentages with Excel, JASP and SPSS in Blackboard)

In Excel, create a data sheet to organize the data shown in question one. Once completed,
generate a bar chart to summarize the frequencies of COVID-19 cases by race, and a pie chart to summarize the percentages of COVID-19 cases by race. (See Frequencies and Percentages with Excel, JASP and SPSS in Blackboard)

Part II. Normal and Non-Normal Distributions
A researcher is interested in determining the resting blood pressure of Drexel University students. To assess blood pressure, 100 undergraduate students were randomly selected to participate in a free health assessment at the university’s health service center, where their resting blood pressure was measured. 1.
Using the JASP dataset provided within the Assignment # 2 folder, generate a histogram for the student’s systolic blood pressure and indicate whether the histogram was normally
distributed, positively skewed or negatively skewed, leptokurtic or platykurtic. (See Normal and Non-Normal Distributions with JASP and SPSS in Blackboard)
The histogram is normally distributed, there is no skew. It is neither leptokurtic nor platykurtic.
Part III. Probability Dr. Bruneau, a faculty member within the Department of Health Sciences at Drexel University has prepared students matriculated in the Exercise Science minor for the American College of Sports Medicine’s Exercise Physiologist exam. Twenty-five of the past 30 students who have taken the exam have passed the ACSM exam.
