Question
A new starch polymer foam with high shock absorbent properties is expected to perform better than
the old foam which can withstand a maximum impact of 1.56 Joule (J). A simple destructive test
to quantify shock absorption ability of the new foam is conducted. Table 5 shows the impact energy
absorbed (in J) that the new foam can withstand for each test.

Does the recorded data suggests that the new foam performs better than the old foam? Use 2.5%
level of significance.
