Listed below we body temperatures from five different subjects measured at 8 AM and again at 12AM Find the values of dandy in general, what dont represent? -Temperature (°F) at 8 AM : 98.2, 99.2, 97.9, 97.9, 97.9

-Temperature (°F) at 12 AM : 99.1, 99.5, 98.2, 97.7, 98.0

Let the toreparature at 8 AM be the first sample, and the temperature at 12 AM be the second sample. Find the values of and µd

d = _________(Type an integer or a decimal. Do not round) µd = ________ (Round to two decimal places as needed.) In general, what does µd represent? O A The mean of the differences from the population of matched data O B. The difference of the population means of the two populations O C. The mean of the means of each matched pair from the population of matched data O D The mean value of the differences for the paired sample data

Answer :

Final answer:

The value of d is 0.9, 0.3, 0.3, -0.2, 0.1. The value of µd is 0.28. In general, µd represents the mean of the differences from the population of matched data.

Explanation:

To calculate the values of d and µd, we need to find the differences between the paired observations and then calculate the mean of these differences.

Given temperatures at 8 AM: 98.2, 99.2, 97.9, 97.9, 97.9

Given temperatures at 12 AM: 99.1, 99.5, 98.2, 97.7, 98.0

To find d, we subtract the first sample (8 AM) from the second sample (12 AM) for each pair:

To find µd, we calculate the mean of these differences:

µd = (0.9 + 0.3 + 0.3 - 0.2 + 0.1) / 5 = 0.28

In general, µd represents the mean of the differences from the population of matched data.
