Part B [20 points]
For this section, you will need to use the BMI Data Excel file and the CDC BMI Group Calculator Excel file.

• Read the Instructions located in the first tab of the CDC BMI Group Calculator Excel file. Then input the raw data from the BMI Data Excel file into the Measurements tab.
• Review the results that are generated by the template in the Group Summary tab. Prepare a short memo of the key findings (in less than 10 sentences) to the County Health Board stating the extent of the obesity problem. How severe would you describe the obesity problem in the county to be? What recommendations would you make to the County to address their problem?

Part C [10 points]
Copy and paste the following table into Excel. Use Excel in order to compute the relative frequency or the probabilities associated with each class interval and fill in the rest of the table. Then answer the questions that follow.
Class Interval Frequency Relative Frequency or Probability Relative Frequency or Probability Expressed as a Percentage
0-4.99 10
5-9.99 15
10-14.99 5
15-19.99 10
20-24.99 10
25-29.99 10

1. What percentage of the measurements are in the range of 10 and 14.99?
2. What percentage of the measurements are more than 15?
3. How many of these measurements are between 10 and 19.99?
4. What is the probability that a randomly selected number will be in the range of 5 and 15?

Part D [10 points]
The following table shows 1,000 nursing school applicants, classified according to scores made on a college entrance exam and the quality of the high school from which they graduated. Use the data in the table to answer the questions that follow.
Score Poor (P) Average (A) Superior (S) Total
Low (L) 105 60 55 220
Medium (M) 70 175 145 390
High (H) 25 65 300 390
Total 200 300 500 1000

• Calculate the probability that an applicant picked at random…
o …made a high or low score on the exam
o …made a low score on the exam and graduated from a superior high school
o …made a medium score or graduated from an average high school
o …graduated from an average high school
• Compare and comment on the probability that an applicant picked at random…
o …made a high score on the exam given that they graduated from a poor high school
o …made a high score on the exam given that they graduated from a superior high school
• Calculate the following probabilities:
o P (AP)
o P (L)
oP(AM)
