Seagulls' food snatching behavior is influenced by human cues such as direction of gaze. So they measured the approach times, in seconds, of gulls to a food source placed close to an experimenter who either (a) looked directly at the gull or (b) looked away The image shows results of a paired samples t-test. Use the results from the image to answer the questions:

What is the value of r2 for the Seagulls.csv data set?

What is the value of Cohen's d for the data?

In simple language explain what the confidence interval tells us.

In simple language, what does the r2 value tell us about the size of the effect that looking at a gull has on its approach time?

What does the value of r2 tell us about the amount of variability explained by the treatment (looking At vs. looking Away)?
