Researchers at a tissue supply company determined that 60 tissues is the mean number of tissues used during a cold. Suppose a random sample of 25 Kleenex tissues users yielded the following data on the number of tissues used during a  cold: X¯  =  52,  S  =  22.   Suppose  the  alternative  you  want  to  test  is   H1 : µ < 60. State the correct rejection region for α = 0.05.       Reject H0 if tSTAT < −1.7109       Reject H0 if tSTAT < −1.6766       Reject H0  if tSTAT  > 1.6766         Reject H0  if tSTAT  > 1.7109
