Which statement is NOT true concerning the t distribution?
A)Compared to the normal distribution, the t distribution has more area in the tails and less in the center.
B)As the number of degrees of freedom increases, the t distribution approaches the normal distribution.
C)The t distributions are skewed to the left.
D)The population variance is unknown and is estimated by the sample variance s2.
E)All are true.

The t distributions are not skewed to the left, as the shape of the t distribution depends on the degrees of freedom. For small sample sizes, the t distribution may appear slightly skewed, but as the sample size increases, the t distribution becomes more symmetric. Therefore, statement C is false.
