1.)
(E) H0: µ 1
H1: µ > 1
The null hypothesis is H0: µ 1 becuase we generally state the null hypothesis as the opposite of what has been claimed in the statament.
Critical value can be seen from the t-disribution table. DF = n - 2 = 13 - 2 = 11
Critical probability will be approximately 2.746.
Since, it is a right-tailed test the first (A) option is the correct option.
t-statistic = 1.1 / (0.2/13) = 19.83
