The
following are brain volumes from 10 randomly selected people. Use
an appropriate hypothesis test with significance level 0.01 to test
the claim that the average brain volume is 1100. You may assume
that any required populations are bell-shaped. 963, 1027, 1272,
1079, 1070, 1173, 1066, 1347, 1100, 1204

Assume that a simple random sample has been selected and test
the given claim. Identify the null and alternative hypotheses,
test statistic, P-value, and state the final conclusion that
addresses the original claim. Listed below are brain volumes in
cubedcm3 of unrelated subjects used in a study. Use a 0.01
significance level to test the claim that the population of brain
volumes has a mean equal to 1100.3 cubedcm3.

Choose the best fitting answer.
Open Brains data. SETUP: Since
females are on average smaller than males, some people believe that
female brains should be smaller as well (smaller volume). Given the
data, your job is to perform the appropriate statistical test or
procedure and help them decide.
