Which of the following correctly compares the t-distribution and z-distribution? A. For small sample sizes, the density curve of the t-distribution is not symmetric, but the density curve of the z-distribution is symmetric.
B. For large sample sizes, the density curve of the t-distribution is not symmetric, but the density curve of the z-distribution is symmetric.
C. The curves of both distributions are symmetric, but the height of the density curve of the t-distribution is taller than the height of the density curve of the z-distribution.
D. The area under the density curve of the t -distribution is greater than the area under the density curve of the z -distribution, especially for small sample sizes.
E. The density curve of the t-distribution is more spread out than the density curve of the z-distribution, especially for small sample sizes.
