The model y = A + Bx is a:




stochastic model



probabilistic model



nonlinear model



deterministic model


To make tests of hypotheses about more than two population means, we use the:



chi-square distribution



t distribution



analysis of variance distribution



normal distribution



A linear regression:


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


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


contains only two variables



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

, A qualitative variable is the only type of variable that:



can assume an uncountable set of values



can assume numerical values



cannot be graphed



cannot be measured numerically

For a one-tailed test, the p-value is:



the area under the curve to the same side of the value of the sample statistic as is
specified in the alternative hypothesis



the area under the curve between the mean and the observed value of the sample
statistic



twice 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 between the mean and the observed value of the sample
statistic

The alternative hypothesis is a claim about a:



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


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


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