A survey of 4276 randomly selected households showed that 4019 telephones (based on data from the US Census Bureau). Minitab was used to test the claim that the percentage of households is now greater than the 35% rate that was found in 1920. The Minitab display is given below. The current rate of 4019/4276 (or 94%) appears to be significantly greater than the 1920 rate of 35%, but is there sufficient evidence to support that claim? Use a 0.01 significance level.
