Which is true about family of t distributions?

As the degrees of freedom increase, the t distributions approach the Normal distribution

t distributions are symmetric and unimodal

t distributions have fatter tails and narrower centers than Normal models

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)

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

because they become less like Normal distribution and more variable and uncertain as the degrees of freedom increase)
