A phone company administers a survey, regarding customer satisfaction.
Based on the survey results, the company provides a confidence interval
estimate of 40% to 70% for customer satisfaction. If the company wishes to
construct a confidence interval that more accurately represents the
proportion of customer satisfaction, how should the design be altered?

my opinion would be to use a larger sample size

3) this final result is transformed up by 5 units.
