Question

In: Statistics and Probability

When a population is divided into subgroups with similar characteristics and then a sample is obtained, this method is called ________ sampling.

When a population is divided into subgroups with similar characteristics and then a sample is obtained, this method is called ________ sampling.
a. Random
b. Systematic 

c. Stratified

d. Cluster

Solutions

Expert Solution

The option (c) is right option.

 

Explanation:

It is stratified sampling, since a stratified sample is a sample obtained by dividing the population into subgroups, called strata, according to various homogeneous characteristics and then selecting members from each stratum for the sample.

 

Hence, the option (c) is right option.


The option (c) is right option.

To evaluate the effect of a treatment, a sample is obtained from a population with a mean of μ = 20 and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 21.3 with a variance of s2 = 9. a. Assuming that the sample consists of n = 16 individuals, use a two-tailed test with α =0.05 to determine whether the treatment effect is significant and compute both...
