Use your calculator to determine the proportion of the standard normal curve that falls within one standard deviation of the mean. Repeat part a) for two standard deviations. Repeat part a) for three standard deviations. Determine the z-score such that the area under a normal curve between it and its negative is 0.5000.

you can use the z-scores and the normal curve to calculate the percentage of data that falls BELOW or ABOVE that data point. You will be using the calculator to help you with this. Calculator Steps: Below the data point: 2nd Vars . Hit 2: normalcdf( -99, value of z – score) Multiply by 100 . Above the data point. 2nd Vars . Hit 2: normalcdf(

Step one – State: P(x > 68) on N(64.5, 2.5) Draw and label a normal curve. Step two – standardize x and label picture with z-score. z = Step three – find the probability by using Table A, and the fact that the total area is equal to 1. Step Four: Write a conclusion:

A score that is 20 points above the mean. z=2. A score that is 10 points below the mean. z=-1. A score that is 15 points above the mean z=1.5. A score that is 30 points below the mean. z=-3. The Welcher Adult Intelligence Test Scale is composed of a number of subtests. On one subtest, the raw scores have a mean of 35 and a standard deviation of 6.

Feb 08, 2015 · The trick to using a Z Score Table like this is to recognize that because the normal distribution is symmetric, the area to the LEFT of z=+0.29 can be found by taking 100% of the area, and subtracting the area to the LEFT of z=-0.29 (what's in the tail).
