Question

#1:       Consider the following small sample of the number of reported cases of contagious conjunctivitis in randomly selected county school districts last week:

36

44

35

45

33

47

1. Compute the sample standard deviationfor this sample data. [COMMENTS & HINTS:A computational table is expected for full credit.  Feel free to utilize software or a calculator to confirm or check your answer.]
2. Compute or report the sample variance.  [COMMENTS & HINTS:Again, feel free to utilize software or a calculator to confirm or check your answer.  This measure is determined as part of the standard deviation computations, correct?]
3. Complete the following reasonable conclusion about the number of reported cases: “On average, there were ## cases of contagious conjunctivitis reported weekly in randomly selected school districts countywide, give or take ## cases.”  
4. Measure the effect sizeby reporting the coefficient of variation, expressed in percentage form.  [COMMENTS & HINTS:There should be no need to round, agreed?]

#2:       Consider the following small population that is the number of high school seniors assigned to each of the five guidance counselors at Palisades Point Academy, a specialized high school focusing on STEM-related studies:

59

41

47

53

50

1. Compute the population standard deviationfor this sample data. [COMMENTS & HINTS:A computational table is expected for full credit.  Feel free to utilize software or a calculator to confirm or check your answer.]
2. Compute or report the population variance.  [COMMENTS & HINTS:Again, feel free to utilize software or a calculator to confirm or check your answer.  This measure is determined as part of the standard deviation computations, correct?]
3. Complete the following reasonable conclusion about the number of seniors assigned to each guidance counselor at the school: “On average, there are ## high school seniors assigned to each guidance counselor, give or take ## students.”
4. Measure the effect sizeby reporting the coefficient of variation, expressed in percentage form.  [COMMENTS & HINTS:There should be no need to round, agreed?]
