Compute a confidence interval about the mean of the differences and select the correct conclusion. (A-B)
A wildlife biologist wants to determine if there is a difference between two radio receivers that are used to track tagged animals
with a collar. The following data represents distance (in meters) of signal from a control collar. Each burst of the signal is read by the
two devices with the following data obtained:
Test the biologists claim that there is a difference in the devices using a 5% level of significance.
Compute a confidence interval about the mean of the differences and select the correct conclusion.
Device A 149 183 119 98 86
Device B 162 187 124 102 92
