We are now ready to calculate the variance of the training values of ? and ?. These values are typically denoted by ?? and ??, and formulas for their calculation are provided below. Sm n-1 and ? = Sp n-1 Create a markdown cell with unformatted text explaining that we will now be calculating the variance of the training values of? and ?. Calculate ? and ??, storing the results in variables named var_x and vary. Print the results with text output as shown below. Round the displayed value of var_x to 2 decimal places, and round the displayed value of var_y to 4 decimal places. Do not round the actual values stored within the variables themselves, just the values displayed. Variance of X = xxxx Variance of Y = xxxx
