What is the purpose of the sample size and the sampling interval?
Homework Answers
The purpose of the Sample size (n) is to determine the Sampling interval (k). The Sample size is collection of consecutive integers that is a part of the Population (N) used for analysis having resembling characteristics.
Sampling interval (k) can be defined as length of string of the consecutive integers. This length of string of sample collection is determined through Population and the Sample Size through formula (k =N/n). Thus, the purpose of the Sampling Interval is essential to know the sampling length to cover the Population. The sampling interval does partitions of the Population into n (Sample size) zonal blocks.
Example:
Population : 1 – 200 numbers
Sample size : 10 numbers ie. 1-10, 11-20, 21-30,……
Sampling interval : 200 / 10 = 20

The purpose of the questions is to hammer home that the distribution of sampling means for a large number of samples always makes a normal curve. 2) The second question concerns the following pair of sample mean distributions: Which distribution came from samples with a larger sample size, the one on the left or the one on the right a) b) Why is the sampling distribution on the right a narrower distribution?

True or False. (Determining sample size n for the purpose of estimating mean) For a specified sampling error (SE) and given population standard deviation, increase in the confidence level (1-alpha) will lead to a larger sample sizen. True False True or False The smaller the p-value associated with a test of hypothesis, the stronger the support for the research hypothesis. True False
