Which of the following is NOT a characteristics of tdistribution? A. B. C. D. Like the normal distribution, the tdistribution has a smooth shape. Like the normal distribution, the Hiistribution is symmetric. If you think about folding it in half at the mean, each side will be the same. Like a standard normal distribution [or zdistribution], the t distribution has a mean of one. The normal distribution assumes that the population standard deviation is known. The tdistribution does not make this assumption. 2. This refers to the measure of position with data divided into 100 parts. Percentiles Quartiles Deciles . Median cows 3.
