Consider a test of coordination that has a normal distribution, a mean of

60, and a standard deviation of 15.

(a) How high a score would a person need to have to be in the top

4%? (Round to nearest integer)

(b) Explain your answer to someone who has never had a course in statistics

In a normal distribution, the percentage of data within a certain distance of the mean is defined in terms of standard deviations. A score that is

1.64

standard deviations above the mean will leave only

of scores greater than that score.

In a normal distribution, the percentage of data within a certain distance of the mean is defined in terms of standard deviations. A score that is

2.05

standard deviations above the mean will leave only

of scores greater than that score.

In a normal distribution, the percentage of data within a certain distance of the mean is defined in terms of standard deviations. A score that is

standard deviations

above the mean will leave only

of scores greater than that score.

In a normal distribution, the percentage of data within a certain distance of the mean is defined in terms of standard deviations. A score that is

1.75

standard deviations above the mean will leave only

of scores greater than that score.
