Problem 99SE

Union negotiation preferences. A union wants to determine the preferences of its members before negotiating with management. Ten union members are randomly selected, and an extensive questionnaire is completed by each member. The responses to the various aspects of the questionnaire will enable the union to rank in order of importance the items to be negotiated. The rankings are shown in the next table. Conduct a nonparametric test to determine whether evidence exists that the probability distributions of ratings differ for at least two of the four negotiable items. Use α = .05.

Survey of Math: Week Two Sets Set: A list of elements separated by commas. Order of elements does not matter. Multiplicity does not matter o Ex: {a, a, a, b, c, c} is the same as {a, b, c} The elements are always contained in {} brackets. This is how you know if you are dealing with a set. Two sets are equal if they have the exact same elements in them. Ex: {a, b, c} = {c, b, a} Cardinality of sets: The number of distinct elements in that set. Ex: If set A= {a, 1, b, 2, c, 3}, then the cardinality of A is six, or │A│= 6, or n│A│= 6. Cardinality can be expressed as │x│= c or n│x│= c where x is the label for the set and c is the cardinality. The empty set: A
