In a hypothesis test, a Type I error occurs when:

• a true null hypothesis is not rejected
• a false null hypothesis is not rejected
• a false null hypothesis is rejected
• a true null hypothesis is rejected

A quantitative variable is the only type of variable that can:

• be used to prepare tables
• assume numeric values for which arithmetic operations make sense
• have no intermediate values
• be graphed

The mean of a discrete random variable is its:

• box-and-whisker measure
• upper hinge
• expected value
• second quartile

For a one-tailed test, thep-value is:

• twice the area under the curve between the mean and the observed value of the sample statistic
• the area under the curve between the mean and the observed value of the sample statistic
• the area under the curve to the same side of the value of the sample statistic as is specified in the alternative hypothesis
• twice the area under the curve to the same side of the value of the sample statistic as is specified in the alternative hypothesis

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

• mean
• population
• sample
• variable

The alternative hypothesis is a claim about a:

• parameter, where the claim is assumed to be true if the null hypothesis is declared false
• statistic, where the claim is assumed to be true if the null hypothesis is declared false
• statistic, where the claim is assumed to be false until it is declared true
• parameter, where the claim is assumed to be true until it is declared false
