Listed below are body temperatures from five different subjects measured at 8 AM and again at 12 AM. Find the values of d-- and sd. In general, what does μd represent? Temperature (°F) at 8 AM 98.2 99.1 97.2 97.7 97.5 Temperature (°F) at 12 AM 99.0 99.8 97.5 97.3 97.9 Let the temperature at 8 AM be the first sample, and the temperature at 12 AM be the second sample. Find the values of d-- and sd. _ d= _________________ (Type an integer or a decimal. Do not round.) sd= ____________ (Round to two decimal places as needed.) In general, what does μd represent? A. The difference of the population means of the two populations B. The mean of the differences from the population of matched data C. The mean value of the differences for the paired sample data D. The mean of the means of each matched pair from the population of matched data
