What is the difference between the t-distribution and the standard normal distribution? A.) the t-distribution has greater area in the tails compared to the normal distribution. B.) the standard normal is bell shaped while the t-distribution is not. C.) the standard normal distribution is symmetric while the t-distribution is skewed. D.) none because they are the same thing. The value added and subtracted from a point estimate in order to develop an interval estimate of the population parameter is known as the A.) interval estimate B.) standard error C.) margin of error D.) confidence leve

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
