90% confidence coefficient
5% confidence coefficient
95% confidence coefficient
10% confidence coefficient
Homework Answers
One sample in 20 may not generate the correct confidence interval, which means that 19 out of 20 may generate the correct confidence interval.
That is 95 out of 100 may generate the correct confidence interval. This is known as 95% confidence coefficient.
