(a) Compute the sample mean and median muzzle velocity.
(b) Compute the range, sample variance, and sample standard deviation.
ANSWER:
Solution
Step 1 of 3
a) We have to compute the sample mean and median from the given data
Mean
=7925.1/10
=792.51
Median
=(10+1)/2 th value
=(5.5)th value
=792.4
Hence Mean=792.51
Median=792.4
