Supposed you were asked to estimate the proportion of 25-30 yearolds that have a home (land line) telephone. In order to make thisestimate, you polled 600 people in this age range and the bellowswere reported below: [25] pts. Total]
           HomePhone             Frequency
           NO                                   450
           YES                                 150
                                                       600
1. What is the proportion of the sample that report YES, theyhave a home phone line? [5 pts]
2. What condition must be met in order to calculate a confidenceinterval to estimate this proportion? Is this condition met? [5pts.]
3. Develop a 95% confidence interval for the proportion of allof 25-30 year olds that have a home (land line) telephone
