This Computing Probabilities for the Standard Normal Distribution: The FDA and Food Safety interactive also includes:
- Introduction to the Normal Curve
- Student Reference
- Join to access all included materials
To recall or not to recall, that is the question. Using provided data, pupils calculate the percent of people that may fall ill on average. The scholars determine the standard deviation based upon the mean and the empirical rule, then use the information to decide whether a given percentage is great enough to warrant a recall.
