Can someone please help walk me through this? Thanks!

Chapter 9, Section 1, Exercise 005 :omputer output for fitting a simple linear model is given below. State the value of the sample slope for the given model. In testing if the slope in the population is different from zero, identify the p-value and Ise it (and a significance level) to make a clear conclusion about the effectiveness of the model. rhe regression equation is Y = 91.9 - 9.14X. Predictor Coef Constant 91.879 x -9.1366 SE Coef 4.662 1.0661 p 19.71 0.000 -8.57 0.000 Sample slope: 7-value: the model effective?
