A sample is selected from a population and a treatment is administered to the

sample. For a hypothesis test with a t statistic, if there is a 5-point difference

between the sample mean and the original population mean, which set of sam-

ple characteristics is most likely to lead to a decision that there is a significant

treatment effect?

it doesnt say anything about the sample so how am i supposed to find the size of it?

a. Small variance for a large sample

b. Small variance for a small sample

c. Large variance for a large sample

d. Large variance for a small sample
