A set of exam scores are reported as Z values and z-scores. On this assignment a score of X=72 corresponds to a z-score of z= +1.00 and a score of X=52 corresponds to a z-score of z= -1.00. What are the values for the mean and standard deviation of this assignment?

The median of any distribution corresponds to a z score of:
a) 0 b) 1 c) N d) cannot be determined from the information given

For a population distribution of o =4, an individual with a deviation score of +2 would have a z-score of:
a) +2.00 b) +8.00 c) +0.50
d) cannot be determined from information given

If a sample mean corresponds to a z-score value near zero, then you can conclude that the sample mean is relatively close to the population mean. True or False?

For a population of U=60 and standard deviation 0=12, find the z-score that corresponds to each of the following X value:
x+ 66, z=?
X= 57, z=?

In any population of scores, at least one individual will have a z-score of zero. True or False?

For a population of u-80 and o-8, find the X value that corresponds to each of the following z-scores:
z= +2.00, X =?
z= -1.25, X=?
Sorry I forgot to add the z scores. Thanks
z= +2.00 X = ?
z=
