A recent study found that the death rate for people who sleep 6 to 7 hours per night is lower than the death rate for people who

sleep 8 or more hours. The 1.1 million observations used for this study came from a random survey of Americans aged 30 to 102. Each survey respondent was tracked for 4 years. The death rate for people sleeping 7 hours was calculated as the ratio of the number of deaths over the span of the study among people sleeping 7 hours to the total number of survey respondents who slept 7 hours. This calculation was then repeated for people sleeping 6​ hours, and so on. Based on this​ summary, would you recommend that Americans who sleep 9 hours per night consider reducing their sleep to 6 or 7 hours if they want to prolong their​ lives

Answer:

Yes, I would recommend those sleeping 9 hours to consider sleeping 6 or 7 hours.

Explanation:

First of all, the sample of the study is very representative because the amount of observations is quite big: 1.1 million!. This means that the results of the study have a very low margin of error, and therefore, can be trusted.

Secondly, the calculations are simple, but correct. The easiest way to determine the mortality rate is to divide the number of people who died by the number of people who are still living, and who belong to the same sample.
