WebThe p value is the evidence against a null hypothesis. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. P values are expressed as … WebThe t-distribution is a type of continuous probability distribution that takes random values on the whole real line. The main properties of the t-distribution are: It is continuous (and as a consequence, the probability of getting any single, specific outcome is zero) It is "bell shaped", in the same way the normal curves are bell-shaped.

"WebZ-Score Table. A z-table, also known as the standard normal table, provides the area under the curve to the left of a z-score. This area represents the probability that z-values will fall within a region of the standard normal distribution. Use a z-table to find probabilities corresponding to ranges of z-scores and to find p-values for z-tests. " - Normal curve hypothesis testing

http://mathcracker.com/t-distribution-graph-generator In statistics, normality tests are used to determine if a data set is well-modeled by a normal distribution and to compute how likely it is for a random variable underlying the data set to be normally distributed. More precisely, the tests are a form of model selection, and can be interpreted several ways, depending on one's interpretations of probability:

This means that the curve of the normal distribution can be divided from the middle and we can produce two equal halves. Moreover, the symmetric shape exists when an equal number of observations lie on each side of the curve. 2. The mean, median, and mode are equal.
