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.

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

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
