Hey there, welcome to numerade.

According to the cdc, adults need at least seven hours of sleep a night.
00:10
So we're trying to conduct a hypothesis test to see if byu students get is different from seven hours a night.
00:18
So for our null and alternative hypotheses here, we have that the population mean is equal to seven hours.
00:28
Whereas the alternative will be the opposite, where the population means does not equal to 7 hours.
00:36
So hence, our decision rule here based on the p value is because, so i denote it as because the p value is less than 0 .05.
01:03
Then what we have here is that we reject the null hypothesis.
01:20
And we have and conclude, so we do have enough information to conclude that the average amount is significantly different, so that the population mean it does not equal to 7...
