Question

Think of a problem that you may be interested in that deals with a comparison of two population proportions. Propose a confidence interval that compares these two proportions.

Two different surveys concluded that cell addiction is indeed a real problem. The first survey conducted on a group of students at a local school in New York ages 15 and 18 years old, shows that 61 out of 220 students have an addiction to their smart phone device. A second survey conducted on adults between 40 and 50 years old shows that 22 out of 80 adults are very much addicted to their smartphone device. Would there be significant evidence that concludes one group has a higher level of addiction then the other.

Please calculate this at a 95% confidence interval
