Question: The following two samples were collected as matched pairs: Pair 1 2 3 4 5 6 7 sample 1 8 4 9.2 8.4 9 7

The following two samples were collected as matched pairs:

Pair 1 2 3 4 5 6 7
sample 1 8 4 9.2 8.4 9 7 3.8
sample 2 7.5 4.6 6 6 1 8 6.0

Calculate the test statistic to test if a difference in means is 5 between the populations represented by Samples 1 and 2.

Use Excel to calculate d and Sd.

Round your answer to two decimal places, and include the zero and the MINUS sign before the decimal place if needed. E.g.,0.12
