hairdresser collected data on the number of services provided on Saturdays and on weekdays. Her results are listed below. Assume the two samples were independently taken. Saturday: sample size = 60 and number of services provided = 24 Weekday: sample size = 45 and number of services provided = 15 1. Estimate the difference in the true proportions with a 99% confidence interval. Show your working. 2. Interpret this interval, in sense what can you conclude about true difference between these two proportions.
