Use a t-distribution and the given matched pair sample results to complete the test of the
given hypotheses. Assume the results come from random samples, and if the sample sizes are
small, assume the underlying distribution of the differences is relatively normal. Assume that
differences are computed using.
Test vs using the paired data in the following table:
Treatment 1 18 12 11 21 15 11 14 22
Treatment 2 18 19 25 21 19 14 15 20
Give the test statistic and the p-value.
Round your answer for the test statistic to two decimal places and your answer for the p-value
to three decimal places.
test statistic = Enter your answer; test statistic
p-value = Enter your answer; p-value
Give the conclusion using a significance level.
a. Reject.
b. Do not reject
