Given a lower bound of 4, upper bound of 8, and sample size n of 1200, calculate the point estimate and margin of error

## Calculate the point estimate:

 Point Estimate  = Upper Bound + Lower Bound 2

 Point Estimate  = 8 + 4 2

 Point Estimate  = 12 2

## Calculate the Margin of Error:

Margin of Error = Upper Bound - Point Estimate
Margin of Error = 8 - 6
Margin of Error = 2

Point Estimate = 6
