Question
Which of the following is not a characteristic of the t distribution? Question 1Select one:a.It is always equal to the z distribution.b.It is a continuous distribution.c.It a symmetric distribution.d.It has a mean of 0.Clear my choice
Solution
The correct answer is:
a. It is always equal to the z distribution.
This is not a characteristic of the t distribution. The t distribution is similar to the z distribution in shape, but it is not always equal to it. The t distribution is more spread out and has heavier tails than the z distribution, especially for smaller sample sizes. As the sample size increases, the t distribution approaches the z distribution.
