On the AP exam, are we allowed to just...say we plugged it into our calculator?

For example, when it says to find the proportion of values on a normal distribution that are between one z-score and another, you can just plug it into your calculator: normalcdf(z1, z2) OR normalcdf(value1, value2, mean, standardDeviation). Instead of wasting our times calculating z-scores or using that table to find proportions, can you just...say you did that?

## Replies to: Extent of calculator use on the AP Stats exam

If your stat teacher has some of these packets, ask to have one so you can get to used to what it looks like. There are some formulas that you may need that aren't on the packet, so make sure you memorize these and how to use them.
