Which group experienced a decline in its percentage each month?

Answer 1

I don’t have the poll you’re referring to. Could you paste the poll data or an image/link to it?

If you’d rather do it yourself, here’s how to answer each question:

- “In February 2013, most Americans identified themselves as …”
- Look at the February 2013 column and find the label with the largest percentage.

- “Which group experienced a net growth over the four months?”
- For each group, compute (percentage in the last month) − (percentage in the first month). Any group with a positive result experienced net growth.

- “Which group experienced a decline in its percentage each month?”
- For each group, check the sequence month by month (Feb → Mar → Apr → May). If the percentage decreases every single month (strictly lower each month), that group experienced a monthly decline.

If you paste the poll values, I’ll identify the answers for you.
