Hi Can I please have help with the following?

Data is on the SALES and PRICE for franchises of a (unnamed) burger chain in a selection of different cities across the US. SALES is in thousands of dollars and is the dependent variable (Y), while PRICE is an index over all products sold in a given month and is expressed as a notional number of dollars for a meal, and is the independent variable (X). The regression output is as attached.1. Using a 5% level of significance, conduct a hypothesis test to determine whether there is evidence that a negative linear relationship exists between PRICE and SALES. Use the critical value approach and interpret the conclusion in context of the question.

2. Find the coefficient of determination and interpret this value. Thank you.
