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 |

Point Estimate = **6**

##### Calculate the Margin of Error:

Margin of Error = Upper Bound - Point Estimate

Margin of Error = 8 - 6

Margin of Error = **2**

##### Final Answers

Point Estimate = **6**

Margin of Error = **2**

##### What is the Answer?

Point Estimate = **6**

Margin of Error = **2**
