Question: A recent survey of 4276 randomly selected households showed that 4019 of them had telephones. 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?
