A test of sobriety involves measuring the subject's motor
skills. Twenty randomly selected sober subjects take the test and
produce a mean score of 41.0 with a standard deviation of 3.7. At
the 0.01 level of significance, test the claim that the true mean
score for all sober subjects is equal to 35.0.

Homework Answers
Here , we should use
Mean Test (1 sample t-test)
Because , we are testing only one population mean.
