The mean weight of junior high school students is µ = 45 kg. If a random sample of 90 students is selected, find the mean and the standard deviation (sampling error) of the sampling distribution. Assume that the standard deviation is 3.5 kg. Select one: mean = 90; standard deviation = 0.3689 mean = 45; standard deviation = 0.3689 mean = 90; standard deviation = 3.5 mean = 45; standard deviation = 3.5
