Question: An outlier can destroy statistical significance. Consider the data in Table 10.4 and the relationship between IBI andwatershed area. The relationship between these two variables

An outlier can destroy statistical significance. Consider the data in Table 10.4 and the relationship between IBI andwatershed area. The relationship between these two variables is statistically significant. Demonstrate the potential effect of an outlier on statistical significance by changing the IBI value of one of the observations in such a way that the relationship between the two variables is no longer statistically significant. The relationship between these two variables is positive. Can you change the data in such a way that the apparent relationship is more positive, that is, by raising the value of IBI for an observation with a large watershed area? Write a short summary of what you have learned from this exercise.
