Please resolve this in Excel $1.$ Two batches of tablets were prepared by two different processes. The potency determinations made tablets from each batch were as follows:

batch A: $5\mathrm{.}1,4\mathrm{.}8,4\mathrm{.}6,5\mathrm{.}3,5\mathrm{.}8,4\mathrm{.}7,5\mathrm{.}7.$

batch B: $4\mathrm{.}8,4\mathrm{.}8,5\mathrm{.}2,5\mathrm{.}3,4\mathrm{.}5,4\mathrm{.}4.$

Test to see if the means of the two batches are the same.
