Jims calculated value for the DurbinWatson statistic is 193

Jim\'s calculated value for the Durbin-Watson statistic is 1.93. Using alpha = 0.05, the appropriate decision is: reject H_0: rho = 0 the test is inconclusive reject H_0: rho = 0 do not reject H_0: rho = 0 do not reject H_0: rho 0 An x chart is being developed using 25 samples of size 8 each. The average of 25 sample means is 6.20. The average of the 25 ranges is 0.30. The lower control limit is What is the forecast for the Period 7 using a 3-period moving average technique, give the following time-series data for six past periods?

Solution

UCL = Avg of sample means + A2 (Avg of ranges)
A2 is found on the chart
= (6.20) + A2 (.30)
= 6.312

Thus correct answer is option first. that is very close value to 6.312
