80
Phone Calls
36
k

Comparing which two values tests whether the way feedback was submitted had an impact on whether or not feedback was positive?

StartFraction j Over j + 36 EndFraction and StartFraction k Over k + 80 EndFraction
StartFraction j Over j + 36 EndFraction and StartFraction 80 Over k + 80 EndFraction
StartFraction j Over j + 80 EndFraction and StartFraction 36 Over k + 36 EndFraction
StartFraction j Over j + 80 EndFraction and StartFraction k Over k + 36 EndFraction

Answer 1

The values tests that will be used to know if the feedback that was submitted had an impact on whether or not feedback was positive is j/j + 80 and 36/k + 36.

How to illustrate the table?

It should be noted that table can simply be used to show the representation of data.

In this case, the values tests that will be used to know if the feedback that was submitted had an impact on whether or not feedback was positive is j/j + 80 and 36/k + 36.

J/j + 80 simply represents the weight of positive emailed responses while 36/k + 36 represents the weight of the positive phoned responses.
