HW 2 For tips on using Minitab, look at “A Quicker Introduction to Minitab”, on the course website. (Click on “Minitab”). Please hand in your Minitab output. (You can copy and paste the Minitab printouts and graphs into a Word document). 1) The file NormTemp.MTP contains data on body temperatures for 130 randomly selected subjects. The first column (Temp) contains the temperatures themselves. For each subject, this temperature, in degrees Fahrenheit, represents an average of several readings taken over the course of two consecutive days. The second column (Gender) is 1 for male, 2 for female, and the third column (HeartRate) is measured in beats per minute. Here, we focus on Temp. A) Make a histogram of Temp. Does the data seem to have a reasonably bell- shaped distribution? Do you see any outliers? B) What do you think the population mean is for body temperatures? (Presumably, you’ve been hearing this number since you were very young! If you were raised on Celsius, convert to Fahrenheit using F=9/5*C+32.) C) Based on the histogram, does the sample mean seem to be reasonably close to the “known” population mean? Don’t actually calculate the sample mean, just look at the histogram. (Hint: If a distribution is symmetrical, then the mean is the center of symmetry). D) Use Descriptive Statistics to calculate the sample mean. What is the value of the sample mean? Is it reasonably close to the “known” population mean? E) Based on the Descriptive Statistics output,
