Question

Determine which variables are significant—at either the 99% or 95% confidence level—and which are not significant at either level. Make sure to choose the highest level of significance for each variable.

Answer 1

The level of statistical significance is often expressed as a p-value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. I think that is correct
