you can still answer the questions.
One thing to keep in mind - in the context of z-scores -

mean.
So a number like -1.40 on a number line would be a smaller
number than -0.2.
But in the context of z-scores, the person who...

two sets of scores. The following test scores were obtained in a
test-retest situation. (Give your answers correct to two decimal
places.)
