The body weight of 500 students in Grade 12 are approximately normally distributed with a mean of 72.9 kilograms and standard deviation of 5 kilograms. If 100 students are randomly sampled: determine the mean and standard error of the sampling distribution of the sample mean find the probability that the sample mean falls between 71 and 73 kilograms the number of sample means that is above 80 kilograms
