Question 1171197: A market survey is conducted by a government regulator to determine the proportion of homeowners who would switch to a new internet service provider if they had the opportunity to do so. Of the 1 200 homeowners surveyed, 800 said that they would switch.
Construct a 99% confidence interval for the population proportion of homeowners who would switch if given the opportunity.
You can put this solution on YOUR website! half-interval is z(0.995)*sqrt((2/3*1/3)/1200)
=2.576*sqrt (1/5400)=0.0351
the point estimate is 0.667
the 99%CI is (0.632, 0.702)
