which of the following statements is supported by the bar chart?
a district 2 has the greatest number of residents who are in favor of the proposal.
b district 1 has the least number of residents who are in favor of the proposal.
c all districts show at least 60% of residents in favor of the proposal.
d in 3 districts, less than half of the residents were in favor of the proposal.
e district 2 has the greatest percentage of residents who are in favor of the proposal.

Explanation:

Step1: Analyze y - axis

The y - axis represents relative frequency (percentage).

Step2: Evaluate Option A

We don't know total residents in each district, so can't say about number of residents in favor.

Step3: Evaluate Option B

Same as A, lack of total - resident data.

Step4: Evaluate Option C

District 1 has relative frequency below 0.6 (60%).

Step5: Evaluate Option D

Only District 1 has relative frequency below 0.5 (50%), not 3 districts.

Step6: Evaluate Option E

District 2 has the highest relative frequency (0.7), so the greatest percentage of residents in favor.

Answer:

E. District 2 has the greatest percentage of residents who are in favor of the proposal.
