Transcribed Image Text:4. A shoe manufacturer claims that athletes can increase their vertical
jump heights using the manufacturer's training shoes. The vertical
jump heights of eight randomly selected athletes are measured. After
the athletes have used the shoes for 8 months, their vertical jump
heights are measured again. The vertical jump heights (in inches) for
each athlete are shown in the table. At a =
evidence to support the manufacturer's claim? Assume the vertical
jump heights are normally distributed
0.10, is there enough
