The information provided on the "Cruffins" worksheet in the data pack can be used to estimate the number of cruffins sold by a coffee shop per day according to the following linear relationship: Number of Cruffins Sold = a+ B(Price) (Regression Equation) a. Using a 5% significance level, conduct an appropriate hypothesis test to determine whether price has a significant negative impact on the number of cruffins sold by a coffee shop per day. b. Calculate and interpret the value of R.
