The interval between the gridlines in an Excel chart is typically blank, but you can highlight the intervals using an alternating pattern by changing the formatting for the gridlines themselves.

Confidence Interval Estimate: a range of values so constructed that a specified proportion of the intervals costructed that way would contain the true value of a parameter. Critical Value: a point on ...

In the estimation of error rates for populations, whose error rate is quite small, the usual assumption of normality can lead to erroneous results. The confidence ...
