Sunshine and sleep

Say you are planning to perform two hypothesis tests:

  • One to establish whether a relationship exists between the number of hours of sunshine per day in London and how many hours per night the residents sleep, and
  • Another to check if exercise is related to blood pressure in elderly men.

Some statements have been provided. Your task is to correctly classify each statement as describing a null hypothesis or an alternative hypotheses for these two tests.
