The Housing Commission of Woodcreek County is interested in finding out more about the number of rental units that do not meet standard living requirements in both Ridge Township and Crystal Township. Units are randomly selected in both cities. Of the 185 units sampled in Ridge Township (call this Township 1), 27 do not meet the requirements. Of the 180 units sampled in Crystal Township (call this Township 2), 34 do not meet the requirements.

a.What proportions of housing units in Ridge Township and Crystal Township do not meet minimum standard living requirements?

b.Find the 95% confidence interval for the difference between the two proportions. How do we interpret this interval?

c.If we decreased the level of confidence to 90%, would the width of the confidence interval be narrower or wider? Why? (Note: you do not need any additional calculations to answer this question.)
