QUESTION 22 As the number of observations/rows in the dataset increase, how does the statistical significance (also known as 'p-value' or Significance Pl of the regression model as a whole tend to change? The model tends to becomes more statistically significant (l.e. p.value decreases) Statistical significance of a regression model is not affected by the number of observations. The model tends to becomes less statistically significant (Le. p.value increases)
