The exam is closed book and closed note. Calculators on cell phone will not be permitted. Dataset: Temp Please load dataset Temp.csv The data was derived from an article in the Journal of the American Medical Association entitled "A Critical Appraisal of 98.6 Degrees F, the Upper Limit of the Normal Body Temperature, and Other Legacies of Carl Reinhold August Wunderlich” and contains temperature, in Fahrenheit, of 130 people. Variable Names: 1. Temp ← Temperature in Fahrenheit 2. Gender ← 1 = Male, 2 = Female 3. Heart_Rate ← Heart Rate (in beats per minute) Question 1 Using Minitab, construct a plot to show the distribution of Temp and determine: Mean of Temp _______________________________________ Standard Deviation of Temp ____________________________ Mean of Temp for Just Males ___________________________ Standard Deviation of Temp for Just Males ________________ Mean of Temp for Just Females _________________________ Standard Deviation of Temp for Just Females ______________ Question 2 A. What proportion of people has a temperature less than 98.6 degrees Fahrenheit for all subjects? B. What proportion of people has a temperature less than 98.6 degrees Fahrenheit for all Males? C. What proportion of people has a temperature less than 98.6 degrees Fahrenheit fall all Females? D. Describe the differences between parts A, B, and C. Which has the largest proportion of subjects and how do they compare overall? Question 3 A. Calculate the 95%, 99%, and 99.9% confidence interval. B. Why does the confidence interval get wider as the percent interval increases? C. Explain what the confidence intervals in part A means. D. A temperature of 98.6 degrees Fahrenheit has been commonly referred to as the normal temperature. Given the 95%, 99% and 99.9% confidence interval is it likely that the population mean temperature is 98.6 degrees Fahrenheit? Question 4 A. Calculate the 95% confidence interval for just males and for just females 95% Confidence Intervals for Males _________________________________ 95% Confidence Interval for Females ________________________________ B. Is 98.6 degrees of Fahrenheit a likely mean temperature for males or females? C. Is it likely that males and females share the same population mean temperature? Explain why or why not.
