a. I would ask a classmate and do whatever they tell me to

b. Cls make sense when we have samples and not the whole population. This is an absurd task and I would respectfully let my professor know that this is not reasonable

c. I would respectfully do what my professor wants because want an A in this class

d. I would use the bootstrap resampling with replacement of the population 10,000 times and compute a pivotal 99% Cl from the histogram of such mean GPAS

O d. Given an effect size, increasing the variability of samples increases power

O a.Given an effect size, increasing the sample size increases power

O b. Given an effect size, increasing alpha cutoff increases power

c. Power is invariant to the magnitude of effect size for a given alpha cutoff and sample size

O a. A 95% confidence interval obtained using the bootstrap approach can be interpreted as "we can be 95% sure that the true measure is in the interval provided"

O b. A bootstrap pivotal confidence interval assumes that the observed sample measure is a pivot such that the variability in sample measures around the true population measure is the same as the variability of measures from the bootstrap resamples around the observed measure

O c.A confidence interval provides an estimate of precision of an effect size

O d. A confidence interval provides an estimate of uncertainty in the sample measure

а.Ranked big-box because the two distributions are unknown

O b. Re-centered two-box because the two groups might come from two different populations

O c. Ranked big-box because there is such a small number of samples that it is better to combine them to make a larger list

O d. Such data should be analyzed using traditional methods such as the t-test

a. One-way ANOVA

O bComparing two groups (independent samples)

O d. Repeated measures ANOVA

O c. Two-way ANOVA

O f. Correlation and regression

Comparing two groups (paired samples)

An ornithologist measures the number of eggs laid per year by two species of thrush in two different habitats. Plotting the data, they create one of the four plots below, where the habitat is on the x-axis (habitat 1 vs habitat 2) and the colors (red vs blue) represent the two species.
