Base on the 3 pictures in the attachment. Answer the following question:
1.
a, Identify your explanatory and response variables and give units for each. 1 pt
b, Identify the strength (weak, moderate, or strong) and the direction (positive or negative) of the relationship in the data and discuss whether fitting a linear model would be reasonable (using the scatterplot and calculated correlation). 1 pt
c, Write the equation of the regression line for predicting your response variable using the R output with your variable names (assume a linear model is reasonable). Interpret the slope of your regression line in the context of your dataset.
