Exam 5: Z Scores, T Scores and Other Normal Curve Transformations

If the mean of a normal distribution were equal to 100, and a raw score of 99 was found to be at the 10th percentile, then

A certain raw score equals 71 and is at the 72nd percentile. The standard deviation is 3.00. What is the mean of the distribution?

When a given raw score value is less than the mean of the raw score distribution, its equivalent z score must be positive.

With a mean of 105 and an SD of 6.30, what raw score falls at the 93rd percentile?

Any raw score which has a percentile rank of 99, has a T score of at least

On a test with a mean of 200 and an SD of 50, what raw score would fall at the 86th percentile?

A z score of -1, indicates a point one standard deviation unit below the mean.

If the mean of an IQ distribution equals 100, with a standard deviation of 15, then an IQ score of 85 is equivalent to a T score of 35.

The T score on a certain distribution is 28. The mean of the raw score distribution is 110, with an SD of 14.93. What is the value of the equivalent raw score?

If a distribution is normal, any percentile can be converted into its equivalent z score.

All T scores greater than 20 must coincide with percentiles which are greater than 50.

When converting z to T, all positive z scores yield T scores

The mean height for a group of children is normally distributed, with a mean of 55" and an SD of 3.71". One child is at the 39th percentile of the height distribution. How tall is that child?

Whenever the percentage values in the z score table indicate an absolute tie

The percentile value for a given raw score must always be at least 50 or above whenever

The raw score distribution always assumes a

The mean equals 60. One individual scores at the 13th percentile and has a raw score of 50. What is the standard deviation?

When the standard deviation of the raw score distribution is equal to less than 1.00, then

In a normal distribution, the mean falls above the 50th percentile only when

The mean is 65, with an SD of 5.00. A raw score of 57 would fall at what percentile?
