Let $\mu_2$ be the mean amount of time second population (sophomores) spent studying for the biostatistics final exam.

So, the hypothesis would be

$H_0:\mu_1=\mu_2$

Since, A professor claims that the mean amount of time (in hours) sophomores spent studying for the biostatistics final exam is more than that of freshmen.

So, alternate hypothesis becomes:

$H_a:\mu_1>\mu_2$
