Suggested answer to exercise: Estimation, standard error and confidence intervals, 4

Question 4: How would the confidence interval change if 99% limits were used?

##
Suggested answer

If 99% limits were used the confidence interval would be wider and more (99%)
of confidence intervals from possible samples would contain the population incidence.
Thus there would be less chance of being wrong but the range of
possible population values would be greater.
(The 99% confidence limits would be 5.8 to 9.2%).
