Instructions: Read each of the exercises carefully. 1. A company that runs a hospital conducted a survey of medical conditions in patients. Build a distribution of relative frequencies. Construct a frequency graph. Construct a pie chart or diagram. Describe and Summarize in your own words the data obtained in the survey. Count cancer types as a separate category. The sample data is as follows: Diabetes Hypertension Diabetes Diabetes Diabetes Hypertension Alzheimer Cancer Breast Parkinson's hypothyroidism Diabetes Diabetes Diabetes Diabetes Diabetes hypertension cancer Colon Cancer of Skin Cancer of Colon Cancer of Breast Diabetes Diabetes Diabetes Diabetes Parkinson's Diabetes Parkinson Alzheimer Hypothyroidism Alzheimer ==================================================== ======================= 2. Construct a time series plot ("Time Series Plot") based on in the incidence of cases in the Emergency area with situations high pressure.

The following data summarizes shark attacks on a beach of northern Puerto Rico since the beginning of the 20th century. In turn, it obtain data on fatalities in shark attacks. A company developing hospitals and medical plans need their technical knowledge in biostatistics. The company needs you to interpret the data and document your findings in written form, after having created the attack graphs of sharks and from tired fatalities avoids that, from sharks. Their interpretation will serve to expand the area of health services in a hospital. The hospital is located in a coastal area close to a beach public. Years Attacks %Fatalities 1900 30 67 1910 25 60 1920 35 55 1930 75 50 1940 100 40 1950 150 50 1960 245 22 1970 150 20 1980 215 10 1990 480 10 Create a time series plot ("time series") for both the number of attacks and percentage of fatalities. Analyze the Graphs and determine what the data reflects. 4. Determine the average beats of the Sample being presented. Determine the value of maximum and minimum beats in the sample. I determined the standard deviation. Find the median and mode of the data. Analyze and describe the beat data provided. Determine the average height of the Sample presented. Determine the maximum and minimum height value in the sample. I determined the standard deviation. Find the median and mode of the data. Analyze and describe the beat data provided.

A Pediatrician wishes to determine the relationship that may exist between the a child's height and head circumference. are selected 11 participants of 3 years and the following data are obtained: Height (in inches) Head Circumference 27.75 17.5 24.5 17.1 25.5 17.1 26 17.3 25 16.9 27.75 17.6 26.5 17.3 27 17.5 26.75 17.3 26.75 17.5 27.5 17.5 Calculate Pearson's correlation coefficient between height and the circumference of a child's head. If the Pediatrician wishes to use height to predict head circumference, is there a relationship between the variables? Discuss and explain her decision.
