Use technology to find(a) the multiple regression equation for the data shown in the accompanyingtable, (b) the standard error estimate and interpret theresult, and(c) the coefficient of determination and interpret the result.

The accompanying table shows the total square footages(in billions) of retailing space at shoppingcenters, the numbers(in thousands) of shoppingcenters, and the sales(in billions ofdollars) for shopping centers for eight years.

Sales y, 123.3, 211.1, 385.9, 475.1, 641.1, 716.7, 768.2, 806.3, 851.3, 893.4, 933.9.

Total sq x₁, 1.4, 2.7, 3.1, 3.6, 4.3, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1.

Shopping x_2, 13.7, 17.9, 21.6, 25.4, 32.7, 37.9, 38.9, 39.5, 40.7, 41.6, 42.1.

(a) What is the regressionequation?
