Normal (or average) body temperature of humans is often thought to be 98.6 F. Is that number really the average? To test this, we will use a data set obtained from60healthy female volunteers aged 18 to 40 that were participating in vaccine trials. We will assume this sample is representative of a population of all healthy females.

The mean body temperature for the 60 females in our sample is 98.010 F and the standard deviation is 0.5340 F. The data are not strongly skewed. Use the Theory-Based Inference applet to find a 95% confidence interval for the population mean body temperature for healthy females. Round your answers to 2 decimal places, e.g. 0.75. The confidence interval is to i eTextbook and Media Based on your confidence interval, is 98.60 F a plausible value for the population average body temperature or is the average significantly more or less than 98.60 F? Explain how you are determining this. 98.60 F is a plausible population average female body temperature because it is not contained in the 95% confidence interval. 98.6. F is not a plausible population average female body temperature because it is not contained in the 95% confidence interval. 98.6. F is not a plausible population average female body temperature because it is contained in the 95% confidence interval. 98.6. F is a plausible population average female body temperature because it is contained in the 95% confidence interval
