- True or false? Given that a confidence interval for µ is 13 +5.
- The value of 13 in this expression is the point estimate.
- The value 5 in this expression is the estimate’s standard error.
- The value 5 in this expression is the estimate’s margin of error.
- The width of the confidence interval is 5.
Homework Answers
a) It is true.
b) It is false.
c) It is true.
d) It is false.
Width of confidence interval = 2* margin of error.
We have given confidence interval is 
where , E= margin of error = 5
