A study is conducted to determine how long a person will wait on hold on a telephone call before hanging up. A sample of 1000 people found that 580 hung up the phone in the first minute of waiting. It is of interest to estimate a range of plausible values for the true proportion of people that will not wait more than one minute on hold. Round all answers to three decimal places.
