Just wondering if someone is able to give instructions as to how to go about this questions?
As part of a large research project, a social psychologist develops a measure of global environmental attitudes (i.e., general attitudes towards the environment). Scores on this
measure are normally distributed, with a mean of ยต=20 and a standard deviation of σ=2.5
What percentage of scores in the distribution are greater than 22?

Z = (scoremean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to the Z score.
