1. Determine the LSRL equation using the format y-mx+b. 2. Describe the slope (m) and its meaning in the context of the data [particularly as it relates to the y-variable]. 3. Use the LSRL you wrote to predict how much of a tip Brianna should expect for a $150.00 order. Does that tip match up with her other tips? Why or why not? 4. Determine the residual for the $102.21 order using the Residual Table. What does this residual tell you about the tip this customer left for Brianna?

Transcribed Image Text:Brianna is a shopper for Instacart. She was wondering if there was a correlation between the amount of an order and the percentage of a tip
that the customer would give her. She collected data from her 10 most recent shopping trips and produced the following information
regarding the relationship between the order amount and the tip percentage each customer gave her.
