6. Which of the following is frue about the t- distibution? A. A t-distribution is composed of bell-shaped curves. Each curve represents a degree of freedom. B. As the sample size decreases, the t-distribution approaches the standard normal distribution. C. Ihe population is not nomally distributed. D. The distribution at the left of the mean is not the same as the distribution at the right of the mean. 7. This table shows the probabilities/areas of the t- distribution for different degrees of freedom. This is used to find the critical values of t. A. c- table C. t- table B. d - table D. z- table 8.
