Upper Actual Sleep in a Typical Night (Hours) Desired Sleep Each Night (Hours) 7.260 8.632

Explanation / Answer

The t value to be used in this case is the desired sleep whose t value is 62.703 , we check the t table for

df = 50

alpha = 0.05

and t = 62.703

and for 2 tail test , as we are interested in the " differ from 8 hours " part

The P-Value is < .00001.

The result is significant at p < .05.

as the p value is less than 0.05 , hence we reject the nulll hypothesis
