A) A 95% confidence interval for the mean weight of all subjects of height 65 inches will be the same width as a 95% prediction interval for the weight of an individual of height 65 inches.
B) A 95% confidence interval for the mean weight of all subjects of height 65 inches will be wider than a 95% prediction interval for the weight of an individual of height 65 inches.
C) A 95% confidence interval for the mean weight of all subjects of height 65 inches will be narrower than a 95% prediction interval for the weight of an individual of height 65 inches.
