Answer #1

to test the negative autocorrelation at significance alpha the test statistic 4-d is compared to the lower and upper critical values dL and dU.

if the Durbin-Watson test 4-d < dL, there is statistical evidence that the error terms are negatively autocorrelated.

i.e., d> 4- dL

therefore option (a) is correct..

    1. You want to test whether you can reject the null hypothesis that a population mean is greater than or equal to 10. To do this, you collect a random sample of size 500 from the population, and you calculate that the sample mean and sample standard deviation are 8.6 and s, respectively. Which of the following is true? a. If s is any value between 11 and 13, you can reject the null hypothesis at the 5% significance level....

    Consider a hypothesis testing situation in which the null hypothesis is p = 0.05 and the alternative is p > 0.5. Data is gathered from a random sample and a test statistic of 2.1 is computed. This means the p-value would have to be: A. less than 0.01. B. between 0.01 and 0.05 C. between 0.05 and 0.10 D. greater than 0.10 E. More information is needed in order to determine the p-value.
