-The samples are dependent
-The two populations have to have uniform distributions
-Both samples are simple random samples
-Either the two sample sizes are large or both samples come from populations having normal distributions or both of these conditions satisfied.

Given :
Here, we want to test a claim about two population means and assume the population standard deviations are not equal.
For this case, following conditions should be satisfied
The samples must be independent.
The two populations have to have uniform distributions
Both samples are simple random samples
Either the two sample sizes are large or both samples come from populations having normal distributions or both of these conditions satisfied.
Step 2
Hence,
The samples are dependent is not true.

A statistic is an unbiased estimator of a parameter when (a) the statistic is calculated from a random sample. (b) in a single sample, the value of the statistic is equal to the value of the parameter. (c) in many samples, the values of the statistic are very close to the value of the parameter. (d) in many samples, the values of the statistic are centered at the value of the parameter. (e) in many samples, the distribution of the statistic has a shape that is approximately NormalConstruct all random samples consisting three observations from the given data. Arrange the observations in ascending order without replacement and repetition.
