A) The mean=25 and the standard error=8. If samples of size n=16 are selected, can we say anything about the(x-bar)distribution of sample means? and if the original x distribution is normal, can we say anything about the (x-bar) distribution of random samples of size 16? Find p(68<=x-bar<=73).© BrainMass Inc. brainmass.com September 21, 2018, 6:40 am ad1c9bdddf - https://brainmass.com/statistics/standard-error/189360
(a) Population mean = 25 and SE of the mean = 8
Sample size = 16, which is less than 30. Therefore, we CANNOT assume normality in the ...
