Also, the study tried to determine whether the number of people waiting behind them has a psychological effect of reducing the annoyance level. A random sample of 16 people who had already been waited in line for 10 minutes at a certain bank were asked to rate their level of negative feelings (annoyance, anxiety) on a scale of 1 (very low) to 5 (very high). The number of people ahead of them and the number behind them were recorded and an interaction term was calculated. Based on the following partial computer output from multiple linear regression analysis, answer parts (a) -(i) below Model Summar Adjusted R Std. Error of the R Square Square Estimate 947* a.
