Jeremy, a point guard on the jv basketball team, connected on 54% of his 3point shots. In his first year on the varsity team he connected on 73 of 120 of his 3-point shots.

(a) Is there sufficient evidence to conclude he is shooting better on varsity than he did as a jv player?

(b) Suppose Jeremy attempts 15 three point shots in the next two games. Could the outcome of these shots change your conclusion from part (a)?
