A paper gives data on x = change in Body Mass Index (BMI, in kilograms/meter) and y = change in a measure of depression forpatients suffering from depression who participated in a pulmonary rehabilitation program. The table below contains a subset of thedata given in the paper and are approximate values read from a scatterplot in the paper.BMI Change (kg/m²)1 1.51.1| 1 0.2 0.20.5 -0.5 0 0.1 0.7 0.8Depression Score Change -144.6131417181214The accompanying computer output is from Minitab.Fitted Line PlotDepression score change = 7.200 + 4.789 BMI changee =7.205.3875621.90%R-SqR-Sq (adj) 14.09%15-10-0.50.00.51.01.5BMI changeR-aq5.3875621.904CoefficientaTermCoefSz Coef7-ValueP-ValueVirConstant7.2002.213.260.0086BMI change4.7892.861.670.12491.00Regression EquationDepression score change = 7.200 + 4.789 BMI change(a) What percentage of observed variation in depression score change can be explained by the simple linear regression model?(Round your answer to two decimal places.)Depression score change (b) Give a point estimate of o.

here as per guidelines i have calculated 3 subparts plz repost with note i need this this... here…
