Use the Bears data file and Bears Data Dictionary to do/answer the following:
1. Explore the data and create a histogram of weight.
2. How many bears had a weight greater than 200 lbs?
3. Create a side-by-side boxplot of age vs sex.
4. What is the median age of female bears in the data?
5. Build a multiple linear regression model using stepwise/mixed (with p-value threshold, enter=0.05, leave=0.1) selection of inputs, predicting weight of a bear. Make any necessary transformations of the data, including adding interactions or quadratic terms. Give your best model's ANOVA table and parameter estimates.
6. Plot the residuals vs. predicted values.
7. What inputs are important in predicting the weight of a bear?
