In an observational study of people’s usage of mobile phones, the mean time spent on voice calls a week was measured. for a specific bootstrap distribution, 0.5% of sample had a mean of 7 minutes or less, 2.5% of samples had a mean of 10 minutes or less, 5% of samples had a mean of 16 minutes or less, 10% of samples had a mean of 20 minutes or less, 90% of samples had a mean of 68 minutes or less, 95% of samples had a mean of 75 minutes or less, 97.5% of samples had a mean of 80 minutes or less, and 99.5% of samples had a mean of 90 minutes or less. what is the 95% confidence interval based on bootstrap percentiles for mobile phones usage?
