Page 198; Exercises 6.1 (1 sheet)
Use the Hospital Charge Worksheet in Chapter 4-1.xls.
a.    Calculate the mean and median for age, LOS, and Charges by using the =AVERAGE ( ) and =MEDIAN ( ) functions.
b.    Based on theses, in what direction are these distributions skewed, if at all?
c.    Calculate the variance and standard deviation of Age, LOS, and Charges by using the formulas in Equation 6.3 and 6.4
d.    Calculate the variance and standard deviation of Age, LOS, and Charges by using the=VAR ( ) and =STDEV ( ) functions. Make sure that the results in (c) match those in (d).
Page 209; Exercises 6.2 (1, 8 a & c only) (1 sheet)
Use the Hospital Charge Worksheet in Chapter 4-1.xls.
a.    Based on the mean and standard deviation for LOS, generate a frequency distribution in terms of one standard deviation units around the mean.
b.    Develop the excel chart to shoe the frequency distribution generated in (a)
Assume the mean is (75) and the standard deviation (5 mmhg) of diastolic blood pressure as given, use the =NORMDIST ( ) function to determine the following:
a. The proportion of people who have diastolic blood pressure less than 76 mmhg
b. The proportion of people who have diastolic blood pressure greater than 73 mmhg
Page 223; Exercises 6.4 (4) Mean and Standard Deviation of a Discrete Numerical Variable (1 sheet)
a. A hospital knows that 0.646 of the persons coming to the emergency room come for true emergencies. Using the formulas in this section and the binomial distribution, calculate the means and standard deviation for any ten arrivals at the emergency room.
Page 227; Exercises 6.5 (1, 2) ( 1sheet)
Use the formula in Equation 6.15 to determine the following standard errors: (1sheet)
1. p = 0.3, n = 80
p = 0.5, n = 80
p = 0.3, n = 250
p = 0.5, n = 250
2. A practice of eighteen dentists upgraded their computer system and suspects that in the process they lost information on recalls for many of their patients. They drew a simple random sample of two hundred patient records and discovered that twenty-two of those had follow-up calls that were not included in the new computer system. Use the = NORMDIST ( ) function to determine the following:
a. The probability that the true proportion of missed follow-up calls is less than 10 percent among all records
b. The probability that the true proportion of missed follow-up calls is greater than 20 percent among all records
