They could turn the lights on and off as they wished. After a month in the room‚ each individual tended to develop a steady cycle. Their cycles at the end of the study were as follows: 25‚ 27‚ 25‚ 23‚ 24‚ 25‚ 26‚ and 25.Using the .05 level of significance‚ what should we conclude about the theory that 24 hours is the natural cycle? (That is‚ does the average cycle length under these conditions differ significantly from 24 hours?) (a) Use the steps of hypothesis testing. (b) Sketch the distributions
