A scientist clаims thаt the cоmmоn cоld cаuses weight to change in adults. The table below gives the weight before infection and one week after. At α = 0.02, is there enough evidence to support the claim that the before and after weight of an adult is different? Assume the before and after samples are random, dependent, and normally distributed.
