Probability--$200 For the definition of probability to be accurate, the outcomes must be obtained by a process called ___________. answer

24
Probability--$300 Provides a complete listing of z- scores and their corresponding proportions of the normal distribution. answer

25
Probability--$400 The _____ always corresponds to the larger part of the distribution, whether it is on the right-hand side or the left- hand side of the distribution. answer
