Question:
Percentage of Telephone Users A recent survey of 4276 randomly selected households showed that 4019 of them had telephones (based on data from the U.S. Census Bureau). Use those survey results to test the claim that the percentage of households is now greater than the 35% rate that was found in 1920. Use a 0.01 significance level. 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?
