Which of the following are assumptions for the Significance Test for the Proportion?

- Data is Categorical;
- Data is from a convenience sample;
- Data is from a Normal Distribution
- nPo and n(1-Po) are both greater than 15
- Data is Quantitative.
**Data is from a random sample.**- nphat and n(1-phat) are both the greater than 15

**Answer:** Data is from a random sample.

## Explanation

The assumptions for a significance test for the proportion are:

- Data is from a random sample.
- [Sample is sufficiently large, which can be assumed to be true when nPo > 15 and n(1-Po) > 15. A significance test for a proportion can be used for both quantitative and categorical data.

We then note that the actual assumptions are:

- Data is from a random sample
- nPo and n(1-Po) are both greater than 15
