+1 pop of differences are approx normal; +1 for qqplot for normality; + 1 each difference is independent
(b) Perform the appropriate t hypothesis test at an alpha = 5% level regarding the research question.
Test statistic and p value (Show computations):
Draw a conclusion in the context of the question:
Suppose that instead of performing the t hypothesis test, the researcher wanted a [two-sided] confidence
interval from a “bootstrap t” distribution. Some relevant quantiles are given for the bootstrap distribution below.
Construct a 95% confidence interval using the bootstrap t distribution.
Bootstrap t value:
