Assume that weights of adult females are normally distributed with a mean of 80 kg and a standard deviation of 22 kg. What percentage of individual adult females have weights less than 77 kg? If samples of 49 adult females are randomly selected and the mean weight is computed for each sample, what percentage of the sample means are less than 77 kg?
