Test the hypotheses: H0 : There is no first-order autocorrelation vs. H1 : There is negative first-order autocorrelation given that: Durbin-Watson Statistic d = 1.75, n = 20, k = 2, and  = 0.01.
 
  What will be an ideal response?

Question 2

Assuming that you are planning to collect data using an experiment, it will be very important to establish an appropriate survey design.
 
  Indicate whether the statement is true or false

Answer to Question 1

dL = 0.86 and dU = 1.27
The decision is made as follows:
If d > 4 - dL = 3.14, reject H0 and conclude that negative autocorrelation is present.
If 2.73 = 4 - dU  d  4 - dL = 3.14, we say that the test is inconclusive.
If d  4 - dU = 2.73, we conclude that there is no evidence of negative autocorrelation.
Since d = 1.75, we conclude that there is no evidence of negative autocorrelation.

Answer to Question 2

FALSE
