Answer: .C. The population is the 10,900 respondents to the American Time Use Survey.
Step-by-step explanation:
In statistics , Population is refer to a large group of individuals or observations that have same characteristics.
A sample is a subset drawn from it.
We are given that "The 2015 American Time Use survey contains data on how many minutes of sleep per night each of 10,900 survey participants estimated they get. An SRS (simple random sample) of 100 of the participants has a mean time of x¯=514.4 minutes. "
i.e. The population is 10,900 respondents to the American Time Use Survey.
All you need to do is multiply 10% of 95 and you will get 9.5 and then subtract that same 9.5 off the 95 dollars and you get 85.5.
Multiply 5 and -2. Then divide by 3.
-10/3 = -3.33333333
This can be rounded to -3.3
Hope this helps!
20/50=2/5=0.4=40%
So yeah, 2/5 or 0.40 or 40%
They're all equal.
Hope this helps.
