23. Population: 2ft 4ft 5ft 6ft True population mean = 4.25ft Estimates*: 2+4 = 3.0ft 2+5 = 3.5ft 2+6 = 4.0ft 4+5 = 4.5ft 4+6 = 5.0ft 5+6 = 5.5ft *Random samples of 2

25. Random sample survey of 1000 people: 25% of sample are edentulous Standard error = 1.4% 95% confidence interval = 22.2%-27.8% (25% + 2 x standard error)
