Q3.
The following are samples obtained from a population that follows a normal distribution
69, 47, 175, 70, 53, 64, 74, 52, 58, 53, 64, 49, 70, 65, 70, 16, 67, 55, 42, 72, 61, 65, 77, 70, 60, 39
-
Find the Sample mean, variance and standard deviation
-
Use them to estimate the parameters of the normal distribution (µ and σ)
-
Find and eliminate any possible outliers.
-
-
Recalculate the sample mean, variance and standard deviation.
-
-
-
Use the new values to recalculate the parameters of normal distribution.
-
-
-
If the population followed Normal (60, 10), did eliminating outliers improve the accuracy of your estimate?
