WebIn probability plots, the data density distribution is transformed into a linear plot. To do this, the cumulative density function (the so-called CDF, cumulating all probabilities below a given threshold) is used (see the graph below). For a normal distribution the CDF will look like an S shape. Web1. The probability that x is between two points a and b is. p (a ≤ x ≤ b) = ∫ a b f (x) dx. 2. It is non-negative for all real x. 3. The integral of the probability function is one that is. ∫ ∞ - ∞ f (x) dx = 1. A continuous probability distribution function can take an infinite set of values over a continuous interval.
WebBased on the above graph, the mean of the dashed normal probability distribution is equal to 30 while the mean of the solid normal probability distribution is equal to 25. Next, based on the given normal curves, we see that the normal curve drawn using a solid line has a wider scope when considering the x-axis.
