Question Set 1_F:
We are going to construct a confidence interval to estimate the
population proportion of all Pennsylvanian adults who own an
iPhone.
First, we must determine if the normal approximation assumptions
are met to compute a confidence interval.

Explain if the assumptions are met by filling in the following blanks:
Because and are both greater than or equal to - (type
the number), then the assumptions
