QUESTION 1

Read the statement below and decide whether it is True or False.

True

False

B. The bootstrap distribution is a distribution of estimates calculated from each of the bootstrap re-samples taken from the population.

True

False

C. A Chi-square test for independence is used to carry out formal analyses on data presented in a two-way table of counts.

True

False

D. The two important components of a regression model are the average pattern (trend) and the deviation of the observations from that pattern (scatter about the trend).

True

False

E. A confidence interval for a parameter is a set of plausible values for that parameter.

True

False

Answer 1

A. If the tail proportion in the re-randomisation distribution is small then the observed difference would be unlikely if chance had been acting alone. TRUE

B. The bootstrap distribution is a distribution of estimates calculated from each of the bootstrap re-samples taken from the population. FALSE.

Here, the correct statement should be that the bootstrap distribution is a distribution of estimates calculated from each of the bootstrap re-samples taken from the sample.

C. A Chi-square test for independence is used to carry out formal analyses on data presented in a two-way table of counts. TRUE

D. The two important components of a regression model are the average pattern (trend) and the deviation of the observations from that pattern (scatter about the trend). FALSE

E. A confidence interval for a parameter is a set of plausible values for that parameter. TRUE
