Your supervisor wants to know if the selected pump design does in fact perform better than the origin pump. Perform a t-test to see if the selected pump provides a higher pressure when compared to origin pump. Original pump pressure measurements are given in Table 2 (pressure values for candidate pun are given in Table.1). Make sure you include things like the null and alternative hypothesis, type of t- test. (15 pts) Table .2 Pressure measurement data for the original pump (in psi).
