Statistics Examples Hypothesis Testing
Determine if Left, Right, or Two Tailed Test
Step 1
Depending on the alternative hypothesis operator, greater than operator will be a right tailed test, less than operator is a left tailed test, and not equal operator is a two tailed test.
Alternative hypothesis has the greater than operator, right tailed test.
Alternative hypothesis has the less than operator, left tailed test.
Alternative hypothesis has the not equal operator, two tailed (left and right) test.
Step 2
The alternative hypothesis operator is greater than which gives a right tailed test.
Right tailed test
