WebbThe functions for calculating probabilities are complex and difficult to calculate by hand. Typically, probabilities are found by looking up tables of pre-calculated values, or by using software and programming. The standard normal distribution is also called the 'Z-distribution' and the values are called 'Z-values' (or Z-scores). WebbStatistical Tables A.1 NORMAL DISTRIBUTION Table A.1 represents the area or probability (a) to the right of speciﬁc z-scores for a normal distribution (see Figure A.1).

Webb31 okt. 2024 · To use the z-score table, start on the left side of the table and go down to 1.0. Now at the top of the table, go to 0.00. This corresponds to the value of 1.0 + .00 = 1.00. The value in the table is .8413, which is the probability. Roughly 84.13 percent of people scored worse than him on the SAT. WebbWe will take zs = 2.58.2 2 You could take the average of 2.57 and 2.58 in this case, that is 2.575 but two decimal places of accuracy is usually enough. Now using the formula we have zs = xs − μ σ 2.58 = xs − 372 40. Rearranging we have, xs = 2.58 × 40 + 372 = 475.2. So applicants who score more than 475.2 will get a scholarship.
