Which of the following statements about the z-distribution (Normal) and t-distribution iš čórréčt? O a. The z-distribution is bell-shaped and symmetric and the t-distribution can be either left or right skewed O b. The z-distribution has a wider spread (width) than the t-distribution O c. The z-distribution has a spread (width) that does not depend on the sample size and the t-distribution has a spread (width) that will decrease when the sample size increases O d. The z-distribution is centered at 0 and the t-distribution is centered at (n - 1)
