Data sets A and B are dependent. Find mean of the differences (d bar).
A 32 30 49 45 33
B 30 26 27 37 24
Assume the paired data came from a population that is normally distributed.

Answer:

9.0

Step-by-step explanation:

Mean = Sum of terms/Number of terms

For Data Set A

Mean = 32 + 30 + 49 + 45 + 33/5

= 189/5

= 37.8

For Data Set B

Mean = 30 + 26 + 27 + 37 + 24/5

= 144/5

= 28.8

Hence, the Mean difference is calculated as the absolute difference between the Mean of Data set A and Data set B

Mean Difference = 37.8 - 28.8

= 9.0
