The quartile deviation of a normal distribution with mean 10 and SD 4 ...
Given, mean = 10, standard deviation = 4.

To find the quartile deviation, we need to find the first and third quartiles.

First quartile (Q1):
Q1 = mean - (0.6745 x standard deviation) [Using normal distribution table]
Q1 = 10 - (0.6745 x 4)
Q1 = 7.302

Third quartile (Q3):
Q3 = mean + (0.6745 x standard deviation) [Using normal distribution table]
Q3 = 10 + (0.6745 x 4)
Q3 = 12.698

Quartile deviation (QD):
QD = (Q3 - Q1) / 2
QD = (12.698 - 7.302) / 2
QD = 2.698 or 2.70 (rounded to two decimal places)

Therefore, the quartile deviation of the normal distribution with mean 10 and standard deviation 4 is 2.70.
