### REVIEW OF HYPOTHESIS TEST FOR ONE PROPORTION ONE-SIDED

HYPOTHESIS TESTING people.stern.nyu.edu. Pele, Before you can determine which test to use, you need to determine how you will measure things. For example, in hypothesis 1, how will you measure вЂњcooperationвЂќ?, ... value x using a t-test. Our null hypothesis is that with a one-tailed test. For example, one-sided alternatives that one could opt to test.
