Are people moving away from having a traditional land line telephone in their homes? A random sample of 153 people was asked “Do you have a traditional telephone in your place of residence?” Of those asked, 95 said they do have a traditional telephone.1. The 95% confidence interval estimate is:a) (0.544, 0.698)b) (0.520, 0.722)c) (0.617, 0.625)d) (0.278, 0.480)2. How large a sample n would you need to estimate p with a margin of error of 0.03 with 99% confidence? Use the approximation the p=0.5 as the value for p in your calculation.a) n=33b) n=153c) n=1068d) n=1844
