s=2,100
n=19

Test the claim about the population mean μ at the level of
significance α. Assume the population is normally distributed.
Write out null and alternative hypotheses, your critical t-score
and your t-test statistic. Decide whether you would reject or fail
to reject your null hypothesis.
