False, Increase the sample size.
When we increase sample size the standard deviation( error) will be decrease and the nagetive skewness is converting to normality. shabirahmad666@rocketmail.com
With probability sampling you have no control over the units that are sampled. So the only way to reduce the margin of error is to increase the size of the sample.
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.
A sample is a subset of the population.

A sample statement can be beneficial in providing guidelines for creating a new statement. Whether the statement be of a written or verbal nature, or whether it be of financial nature, following a sample can be beneficial.
One of the ways to reduce survey errors is to take samplings from all of the population. Do not only sample certain demographics. Another way to reduce errors is to remove those who do not respond. By leaving the total number of surveys the same, the results are not accurate. Do not count those with no answer in the total number of surveys.
The width of the confidence interval willdecrease if you decrease the confidence level,increase if you decrease the sample sizeincrease if you decrease the margin of error.
it should decrease
The statement is false. For a fixed alpha, an increase in the sample size will cause a decrease in beta (but an increase in the power).
It will decrease too. * * * * * If it is the confidence interval it will NOT decrease, but will increase.

A large sample will reduce the effects of random variations.
