v n.\"- I UIILIMJ Current Attempt in Progress Computer output for tting a simple linear model is given below. State the value of the sample slope for this model and give the null and alternative hypotheses for testing if the slope in the population is different from zero. Identify the pvalue and use it (and a 5% signicance level) to make a clear conclusion about the effectiveness of the model. The regression equation is Y = 87.0 0.01 18X.
