1) Given the following information. Fill out the suma, squareds, and products columns rows: Hours Bludied Mark on Exam 40 74 28 a) Perform a linear regression by hand you must show ALL steps for mark (3] by Calculate the correlation coefficient by hand you must show ALL steps for marks (2) ch Classify the correlation based on b) [1] dj Using Desmos (https /www.desmos.com/calculator), perform a linear, exponential, and power regressions [=] Btop 1: Input the table into desmos using the values for hours studied and mark on exam Btop 2: Perform all regressions. Linear, Exponential, and Power A Btop 3: Record the outputs Equation (Fill in the appropriate parameters Correlation Coufficiant squared [r ] given from Desmos) Coofficiant of Determination (N) Linear Exponential Power ") Which model is the best regression? Explain Nore: you have to compare the squared correlab with the coefficient of determinations [2]
