... How can we do that? In the scientific community we are not allowed to just say, “Well clearly A is bigger than B!” Even though the results of an experiment are sometimes obvious, we have to have some kind of separate measure to indicate to anyone who looks at our results that there really is a diffe ...

... we require two standard scores. Give one of these standard scores, but do not calculate it out or use the z-table. Scores are (4.5-7)/Sqrt[7] and (5.5-7)/Sqrt[7]. The area between these standard scores on the z-curve is an approximation of p(5) using the continuity correction. 3. R.v. X has the foll ...
