Question 6

(5 points)

Question 6 options:A normal distribution of test scores has a mean of 38 and a standard deviation of 6. Everyone scoring at or above the 80th percentile gets placed in an advanced class. What is the cutoff score to get into the class?

Enter answer rounded to the nearest hundredth (2 places after decimal). Examples of correctly entered responses:

0.84     12.03      20.50     76.18   100.00

View hint for Question 6

When using the “Inverse Normal Distribution Area Calculator” you’ll be asked to enter “Area”. Notice on the calculator’s graph that the area is shaded from the right (from 100% back). If you want “80th percentile”, that means a cumulative probability of 80% which is always measured from the far LEFT of the curve. If “0.80” is measured from the far left of the curve, then (1 – 0.80) is what remains to the right of the curve. If you want to know the area that’s ABOVE the 80th percentile, be sure to enter “0.20” under “Area”, then select “Above” in next step and “recalculate”. Raw score readout will appear.

Remember, cumulative probability is always measured from the LEFT end of the curve!
