  • The Null Hypothesis That The Overall Slope Is Zero

    616 Words  | 2 Pages

    The given reports the P value testing the null hypothesis that the overall slope is zero, the best fit value of the slope is 0.00. The P value answers the question: If the true slope is zero, what is the chance that the slope will be further from zero than the observed slope due only to random sampling. Since the observed slope is zero, there is almost a 100% chance of obtaining a slope that is further than zero than observed! So the P value is greater than 0.99, as high as a P value can be. Some

    batteries (CEPA, n.d.). Null Hypothesis Based on the claim, the null hypothesis is H0: The number of battery electric cars in the city is 10%. Notably, the claim forms H0 because it contains the equality sign (Triola, 2012). In symbolic form, we express the null hypothesis as H0: p = 10%. Alternative Hypothesis The alternative hypothesis for the claim is H1: The number of battery electric cars in the city is not 10%. In symbolic form, we express the alternative hypothesis as H1: p ≠ 10%. Initial

    jointly not significantly different from zero. The statistic for this test is where T is the sample size, m is the number of lags and is the estimated autocorrelation coefficient. The null hypothesis for this test is that the coefficients are all jointly zero and has a distribution. The alternative hypothesis is that at least one of the coefficients is not equal to zero and implies the presence of serial correlation. We can estimate the Ljung-Box statistic in Eviews by creating a correlogram
