Tests of older baseballs showed that when dropped 24 ft onto a concrete surface, they bounced an average of 235.8 cm. In a test of 40 new baseballs, the bounce had a mean of 235.4 cm. Assume the standard deviation of baseball bounce heights is 4.5 cm. At α=0.05, are the new baseballs different?
A. There is sufficient evidence to support the claim that the new baseballs have bounce heights with a mean different from 235.8 cm
B. There is not sufficient evidence to support the claim that the new baseballs have bounce heights with a mean matching 235.8 cm
C. There is sufficient evidence to support the claim that the new baseballs have bounce heights with a mean matching 235.8 cm
D. There is not sufficient evidence to support the claim that the new baseballs have bounce heights with a mean different from 235.8 cm
