The mean and variance of a comparison distribution that would be used to test the hypothesis that the mean obtained in a study involving 10 participants is different from a known population having a mean of = 100 and 2 = 25 would be
A) mean = 10, variance = 2.5
B) mean = 10, variance = 5
C) mean = 100, variance = 2.5
D) mean = 100, variance = 5
Question 2
The comparison distribution for the mean of a sample is the distribution of means because
A) comparing the mean of a sample to a distribution of a population of scores of individuals is a mismatch.
B) the available population parameters are inaccurate and reflect too little variance within the population.
C) the distribution of means is likely to have more varied scores than would be represented in the population.
D) the proper comparison distribution is stated in the research hypothesis.
