Q1. Data Exploration (10 points) Use the dataset “supply_chain” for this question a. (2 points) Is the response variable Replenishment_Cost normally distributed or skewed? b. (2 points)  Which product type has the highest average Replenishment_Cost? c. (2 points) Calculate the correlation coefficient and plot a scatterplot between Order_Quantity and Lead_Time. Do products with higher Order_Quantity tend to have lower Lead_Time? d. i) (2 points) How does the distribution of Replenishment_Cost vary across different Regions, and are there any outliers identifiable in each region? ii)(2 points) Test whether the mean Replenishment_Cost significantly differs across the four Region categories?
