The formula for the t test is: The degrees of freedom are d.f. = n–1. Example 1: Find the critical t value for with d.f. = 16 for a right-tailed t test. Example 2: Find the critical t value for with d.f. = 18 for a right-tailed t test. Example 3: Find the P-value and decide whether to reject or not to reject Ho.

(b) Locate the two critical values t* from Table D that bracket t. (c) Between what two values does the P-value of the test fall (From Table D)? (d) Is the value t = 2.40 statistically significant at the 5% level? At the 1% level? (e) If you have software available, find the exact P-value. 7.25 Random distribution of trees t …

Depending on the size of the workshop, it may be advisable to break off into smaller groups to allow more in-depth discussions. Thorough discussions and reviewing of evidence, ensure that a consensus score (see table 1) is given to reach an overall score for each track. When appropriate, evidence should be collected to justify the scoring.

To look up 2.43 on the border of the table, we notice that down the left-hand side of the table it shows 0.0 to 3.0, and across the top of the table it shows 0.00 through 0.09. Use 2.4 (from 2.43) to find the row of the table that we need, and use 0.03 (the rest of 2.43) to find the column.
