The following scenarios each contain enough information to carry
out a hypothesis test for means. For each one, (1) give the formula
for the test statistic (in terms of the variables, not the numbers
in the problem!), (2) indicate which distribution you would use to
determine the critical value, and (3) give the number of degrees of
freedom, either as a formula or as calculated for the problem (if
relevant). You don’t have to explain your answers, and you don’t...
