Why is the normal distribution so important? Answer Choices: Because the probability of getting a normal distribution of scores from sample data depend on the method of selecting the sample. Because it is a symmetrical distribution. Because the ends never intersect with the X axis. Because we can use it to estimate the probability of events occurring in the population based on sample statistics.
