Does computer-assisted instruction help community college health students with reading difficulties to learn reading skills at a faster than normal rate? A researcher arranged for one of these students to have access to a set of computer-learning programs instead of the normal reading curriculum for one term. At the end of the term, the researcher tested her on a standardized reading ability test on which the mean for students with reading difficulties is 36 with a standard deviation of 6. The test participant scored 47. Was this result significant at the .05 level?
Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score.
