The demand for hand sanitizers is off the charts due to this coronavirus outbreak. People are in desperate need of hand sanitizers. Therefore, FMCGs like Unilever Bangladesh Limited are producing this life-essential product in a bulk amount to help the citizens across Bangladesh to maintain the hygiene standards. Sales figures and profits for the stores are given in the following table. (For the Unit sales, pick any value in between 12-33Units in ascending order). Unit Sales, X Profit (Taka), Y ** 1200 ** 1650 ** 1950 ** 2300 ** 2700 ** 3600 ** 4100 Obtain a regression line for the data. Calculate the profit of a shop for 40 unit sales. Calculate the correlation between unit sales and profit. What is the coefficient of determination of these variables?
