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

<-- Lower Bound
<-- Upper Bound
<-- n
  
Given a lower bound = 4, upper bound = 8, and sample size n = 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

Point Estimate = 6

Calculate the Margin of Error:

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