Cоpy the dаtа here intо Excel аnd run a regressiоn with Y as the dependent variable and X as the independent variable. There are 14 observations; be sure to copy all of them. a) R square is [rsq]. b) The predicted value of Y when X is 1.4 is [pred14]. c) The predicted value of Y when X is 2.5 is [pred25]. d) The estimated slope of the regression line is [slope]. e) Consider the null hypothesis that the slope is 0.5. Test this hypothesis. The test statistic is [test5]. f) For this test, that the slope is 0.5, at the .05 level of significance you [result5]. g) Consider the null hypothesis that the slope is 0.7. Test this hypothesis. The test statistic is [test7]. h) For this test, that the slope is 0.7, at the .05 level of significance you [result7]. i) Provide the 90% confidence interval for the slope in the regression: [lower] to [upper].
