q2 i? The coefficient of total time spent squared is positive and statistically significant, indicating the negative effect of time decreases as time increases. → Ipinnaiye 2024

Same regression analysis. The study reports that "we find that the coefficient of total time spent squared is positive and statistically significant (β = 0.000036, p = 0.072 < 0.10)", suggesting a certain level of time investment is required to realise benefits.
