Question: Suppose we use the R command below, where Group is a categorical variable with values A, B, and C. lm( Y ~ X + Group

Suppose we use the R command below, where Group is a categorical variable with values A, B, and C. lm( Y ~ X + Group , data=BronlynsExamData) We are given the summary statistics below: Variable Estimate of coefficient p-value (intercept) 2 Less than 0.0001 X 1.5 Less than 0.0001 Group B -4.8 Less than 0.0001 Group C -5 Less than 0.0001 True or False: From this model, we can conclude that when we control for X, there is a statistically significant difference in average Y when comparing group B with Group C
