Of the 100 people, your group surveyed 53 people surveyed said
they follow Aeron Chanda was found to have 8 less than Aeron Bela

Sample information: 24 out of 1000 people who were surveyed had
type 2 diabetes. Use the above sample information and construct two
confidence intervals (one with confidence level of 90% and the
other one with confidence level of 99%) to estimate the proportion
of people who have type 2 diabetes. What is the relationship
between the confidence level and the size of the confidence
interval? Is this significant? Why is it important to understand
this concept?
