Question

-when a value is plugged in for x in a regression equation, the output value calculated y prime is now as : pt

estimate, avg value, set of standard dev, modal value

-when performing a hypothesis test to determine correlation, the null hypothesis is always equal to zero, meaning that until proven otherwise we assume there is no correlation:t or f

-correlation is determining whether a relationship exists between an input _____ variable and output______ variable: all, controllable and noncontrollable, x & y, independent, dependent

-if the correlation coefficient is 0.790, what is the explained variation: 62.4 or 21 %

-the cause and effect relationship of an input variable may be that the output variable is also affected by an unknown second input variable called: lurking, constant, zeroing, or dependent (variable)

-the null hypothesis states that there is a significant difference between the accepted value of a variable and the findings for that variable in a statistical test: t or f

-the standard error of the estimate is the standard deviation of the observed x-values about the predicted x-values: t or f
