Interpret what you see (or think you see).Use Excel to estimate a simple linear regression between these two variables.Interpret the meaning of R2 and comment on its magnitude.(70 words)Interpret the meaning of ?0 and ?1. (70 words)Use the standard, simple regression equation to predict the mean distribution cost of 1000orders.6. Explain the statistical significance of the slope in this solution.
