A researcher conducts two t tests. Test 1 is a one-tailed test
with a smaller sample size at a .05 level of significance. Test 2
is a one-tailed test with a larger sample size at a .05 level of
significance. What do you know about the critical values for each
test?

For each of the following two-samples t-tests (problems
1-6): (a) Determine if a F test for the ratio of two variances is
appropriate to calculate for the context. If it is appropriate,
conduct the analysis and report the result. Include what
statistical conclusion you should draw from the analysis (i.e.,
whether you should conduct a pooled-variance t-test or an
unequal-variances t-test). (b) Identify the most appropriate t-test
to conduct for the situation/data given. Don’t forget to consider
if the context...

For each of the following samples that were given an
experimental treatment, test whether the samples represent
populations that are different from the general population: (a) a
sample of 11 with a mean of 46, (b) a sample of 1 with a mean of
