Since probability tables cannot be printed for every normal distribution, as there is an infinite variety of normal distribution, it is common practice to convert a normal to a standard normal and then use the z-score table to find probabilities. Z-Score...

Definition of Z-Score Table A standard normal table that is also known as the z-score table or Z-Score Table, is basically a mathematical table used for the values of ‘ϕ’. These values are of the cumulative distribution function of a usual distribution. However, the Z-Score also ...
Step 3:Write the standard deviation, σ into the formula. Step 4:Find the answer using a calculator: (1100 – 1026) / 209 = .354. This means that your score was .354 std devs above the mean. Step 5:(Optional) Look up your z-value in thez-tableto see what percentage of test-ta...
