(c) The predictors that were found to have significant coefficients from the t tests are the same ones that are significant from using the
p-values.
O True
O False
(d) When checking for significance, most prefer the p-value approach because
O The p-value actually tells the strength of the significance.
O It is easier than looking up a critical value for the t statistic.
