Question: For our class project we asked people if the rented or owned their current residence. Here are the results for people in the different age groups:

a. Calculate a point estimate and 95% confidence interval for the proportion of each age group that owns their current residence. Make a statement about the confidence interval for each group.

b. Calculate the margin of error for these point estimates. Use them to make a statement about the proportion of people that owns their current residence.

c. Does our data support this statement: “People in their 40’s and 50’s are more likely to own their residence than are people in their 20’s and 30’s.” Use the point estimates and confidence intervals to explain your reasoning.
