True : t -distributions are symmetric and unimodal (just like normal distributions)


(False : As the degrees of freedom increases the t p distribution approach the Normal distribution

because they become less like Normal distribution and more variable and uncertain

False: T- distributions have fatter and narrower centers than Normal distribution because they have broader centers and narrower tails)
