note that these participants all said they would pay not to receive the shock in an earlier portion
of the study! Is there significant evidence that men have a harder time sitting alone with their
thoughts (i.e administered more shocks) than women?
(a) State the hypotheses for the test.
(b) Calculate the test statistic.
(c) Find and interpret the p-value.
(d) State the conclusion of the test.
(e) Based on the conclusion, do you expect a confidence interval to contain zero? Explain
without constructing the interval.
104. Referring back to the interesting series of tests by Wilson et. al. in Science 2014, participants
were asked to sit alone with their thoughts for 15 minutes. Researchers wondered if it was hard
for participants to sit alone with their thoughts because of the unfamiliar laboratory setting.
Therefore, some subjects were allowed to complete the experiment at home. The 146 partici-
pants completing the experiment in the lab had a mean "enjoyment score" of 5.12 with standard
deviation 1.77. The 44 participants completing the experiment from home had a mean "en-
joyment score" of 4.35 with standard deviation 1.95. Is there significant evidence to conclude
that environment (home vs. lab) caused a difference in mean enjoyment score? Perform the
appropriate test.
