Run the COMBINATION program to fi nd the smallest distance between the two means in which a bimodal distribution is still apparent (the second mean doesn’t need to be a whole number, i.e., 8.5 and 5.75). If the means of the two popula-tions are close together, then it is appropriate to consider that the two populations are similar.


a. What is the smallest distance between the means for which a bimodal distri-bution is still apparent? __________.


b. Statistical analyses are generally valid only for data that are randomly sam-pled from a symmetrical unimodal population distribution. What can you do to verify that a certain sample of data was randomly selected from a sym-metrical unimodal (normal) population?
