SAMPLING DISTRIBUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Increasing the sample size of sample will reduce the
A
bias.
B
variability.
C
mean.
D
nothing, it will stay the same.
Explanation: 

Detailed explanation-1: -As the sample sizes increase, the variability of each sampling distribution decreases so that they become increasingly more leptokurtic. The range of the sampling distribution is smaller than the range of the original population.

Detailed explanation-2: -The reason is that increasing sample size will not only reduce bias, but will eliminate the variance effects of sampling error.

Detailed explanation-3: -Assuming 100% effective 100% inspection, the variability is reduced by identifying and then scrapping or reworking all items that have values of Y beyond selected inspection limits. The more the limits are tightened, the greater the reduction in variation.
