(a)
Find the value of t.10,15
(a)
Explanation of Solution
The table for t value is as follows.
Table 1
v | t.100 | t.050 | t.025 | t.010 | t.005 |
13 | 1.350 | 1.771 | 2.160 | 2.650 | 3.012 |
14 | 1.345 | 1.761 | 2.145 | 2.624 | 2.977 |
15 | 1.341 | 1.753 | 2.131 | 2.602 | 2.947 |
To find the value of t.10,15, have to match the values of rows and columns correspond to 15 and t.100 respectively and check on which value they are intersecting. Then, here the t value will be 1.341.
(b)
Find the value of t.10,23
(b)
Explanation of Solution
The table for t value is as follows.
Table 1
v | t.100 | t.050 | t.025 | t.010 | t.005 |
21 | 1.323 | 1.721 | 2.080 | 2.518 | 2.831 |
22 | 1.321 | 1.717 | 2.074 | 2.508 | 2.819 |
23 | 1.319 | 1.714 | 2.069 | 2.500 | 2.807 |
To find the value of t.10,23, match the values of rows and columns correspond to 23 and t.100 respectively and check on which value they are intersecting. Then, here the t valuewill be 1.319.
(c)
Find the value of t.025,83
(c)
Explanation of Solution
The table for t value is as follows.
Table 1
v | t.050 | t.025 | t.010 | t.005 | t.0025 |
81 | 1.6639 | 1.9897 | 2.3733 | 2.6379 | 2.8859 |
82 | 1.6636 | 1.9893 | 2.3727 | 2.6371 | 2.8850 |
83 | 1.6634 | 1.9889 | 2.3721 | 2.6364 | 2.8840 |
To find the value of t.025,83, match the values of rows and columns correspond to 83 and t.025 respectively and check on which value they are intersecting. Then, here the t value will be 1.9889.
(d)
Find the value of t.05,195
(d)
Explanation of Solution
The table for t value is as follows.
Table 1
v | t.050 | t.025 | t.010 | t.005 | t.0025 |
193 | 1.6528 | 1.9723 | 2.3458 | 2.6015 | 2.8397 |
194 | 1.6528 | 1.9723 | 2.3457 | 2.6014 | 2.8395 |
195 | 1.6527 | 1.9722 | 2.3456 | 2.6013 | 2.8393 |
To find the value of t.05,195, match the values of rows and columns correspond to 195 and t.195 respectively and check on which value they are intersecting. Then, here the t value will be 1.6527.

The researcher uses 3 different forecasting models: A, B and C. Model A is an AR(1) model with no drift and with an estimated autoregressive coefficient = 0.7. Model B is a MA(1) model with no constant and with an estimated MA coefficient = -0.4 (note the minus !). Model C is a random walk model with no drift.
