S.P.2.2 Confidence Intervals and Sleep
I will be able to determine that a sample meets the conditions for a margin of error. I will be able to use critical values to create a margin of error for a certain confidence level. I can find confidence intervals.

Multiple Choice
Condition #1: Is this a random sample?

Multiple Choice
Condition #2: 10% condition. Is 1029 U.S. adults less than 10% of the U.S. population (U.S. population is about 331 million people)

Multiple Choice
Condition #3: Large count. Is 1029 x 0.48 and 1029 x 0.52 greater than 10?

Conditions met
Now that all three conditions are met we can find the margin of error using critical values and the standard error formula.
