In 1998, statistics canada reported that 36% of canadian households use the internet. George polled 100 households in his neigbourhood to see if they use the internet more often then the national averga.
A.)Construct a 99% confidence interval for the number of households that use the internet.
sample proportion: 0.36
margin of error:::2.326*sqrt(0.36*0.64/sqrt(100) = 0.3531
99% CI: 0.36 - 0.3531 < p < 0.36 + 0.3531
99% CI: 0.0069 < p < 0.7131
