Or anyone who learned z-scores. How do you use it? I always got confused.
The number of hours that college student sleep on a weeknight is approximated by a normal curve with a mean of 7 hours in a standard deviation of 1.7 hours. Answer the question below using z table.
On weeknights, what percentage of students sleep between 5 and 10 hours? (Round to whole number)
A) about 95%
B) about 40%
C) about 84%
D) about 80%
Don't really know what to do. Do y'all? -
