0 smokers were questioned about the number of hours they sleep each day you want to test the hypothesis that the smokers need less sleep than the general public which needs an average 7.7 hours of sle?
Disclaimer: This is not an easy answer because a lot depends on the sample size, distribution of population, etc. But for the sake of this I will assume that we are talking about a normally-distributed population and a sufficiently large sample size.You want to test the hypothesis that smokers need less sleep than the general public. You are told that the general public needs an average of 7.7 hours of sleep. So:Avgpop = 7.7The hypothesis that you are testing (H1) is that smokers need less sleep:Avgsmoker < Avgpopulation or Avgsmoker < 7.7 hoursYour null hypothesis (Ho) would be that there is no difference between the two groups OR that smokers need MORE sleep than the general population:Avgpopulation >= Avgsmoker or Avgsmoker
