The mean of a discrete random variable is its:

 upper hinge

 expected value

 second quartile

 box-and-whisker measure

 

​If you divide the number of elements in a sample with a specific characteristic by the total number of elements in the sample, the dividend is the:

 sample mean

 sample proportion

 sampling distribution

 sample distribution

 

We can use the analysis of variance procedure to test hypotheses about:

 the mean of one population

 two or more population proportions

 two or more population means

 the proportion of one population

 

​The alternative hypothesis is a claim about a:

 parameter, where the claim is assumed to be true until it is declared false

 statistic, where the claim is assumed to be false until it is declared true

 statistic, where the claim is assumed to be true if the null hypothesis is declared false

 parameter, where the claim is assumed to be true if the null hypothesis is declared false

A linear regression:

 gives a relationship between two variables that can be described by a line

 gives a relationship between two variables that cannot be described by a line

 contains only two variables

 gives a relationship between three variables that can be described by a line

 

​In a one-way ANOVA, we analyze only one:

 sample

mean

​population

variable
