In this lesson, this section (76% complete) states:
"We already know the significance and power levels that we want and we are interested in a one-sided test. In this case, our one-sided test applies only to the case when the true speed is GREATER or equal to 10 miles per hour above the posted speed limit. Therefore, we will specifiy the test type as "greater"."
Above, the lesson had stated that the goal was to be able to detect a mean speed that was 5 MPH or more than the speed limit.
Thank you for checking this conflict in the lesson. (Also, there is a small typo in specify above.)
