Given a lower bound of 17, upper bound of 27, and sample size n of
calculate the point estimate and margin of error
Calculate the point estimate:
| Point Estimate |
| Upper Bound + Lower Bound |
| Point Estimate |
| 27 + 17 |
| Point Estimate |
| 44 |
Point Estimate = 22
Calculate the Margin of Error:
Margin of Error = Upper Bound - Point Estimate
Margin of Error = 27 - 22
Margin of Error = 5
Final Answers
Point Estimate = 22
Margin of Error = 5
