E) adding squared standard normal distributions 6 An F distribution is obtained by (Points: 6) A) dividing two chi-square distributions, each adjusted by its degrees of freedom B) dividing a standard normal distribution by the square root of a chi-square distribution which been adjusted by its degrees of freedom. C) dividing a t distribution by the square root of a chi-square distribution which has been adjus its degrees of freedom D) adding squared standard normal distributions E dividing the square root of a chi-square distribution which has been adjusted by its degrees freedom by the square root of another chi-square distribution which has been adjusted by its degr freedom Which of the following distributions is NOT symmetric?
