As the automobile accident rate increases, insurers are forced to increase their premium rates. Companies such as Allstate have recently been running a campaign they hope will result in fewer accidents by their policyholders. For each six-month period that a customer goes without an accident, Allstate will reduce the customer’s premium rate by a certain percentage. Companies like Allstate have reason to be concerned about driving habits, based on a survey conducted by Drive for Life, a safety group sponsored...

A statistics student at a New York State community college, randomly samples 900 students who own cell phones to determine if they play games on their phones. 75% stated that they use their mobile phones to play games. Using this information, then: construct a 90% confidence interval (to 4 decimal places) for the population proportion, p, of NYS community college cell phone users who play games on their phones. construct a 99% confidence interval (to 4 decimal places) for the...
