Listed below are body temperatures from five different subjects measured at 8 AM and again at 12 AM. Find the values of d and So. In general, what does ud represent? Temperature (F) at 8 AM 98.2 99.3 97.2 97.9 97.4 Temperature (F) at 12 AM 98.7 99.6 97.5 97:8 97.8 . . . . . 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 Sa. d = (Type an integer or a decimal. Do not round.) So = (Round to two decimal places as needed.) In general, what does Hq represent? O A. The mean of the differences from the population of matched data O B. The mean of the means of each matched pair from the population of matched data O C. The mean value of the differences for the paired sample data O D. The difference of the population means of the two populations
