a) Fill in the population of the table to the nearest 1000.

b) Write the population in ascending order.

Let's address each part of the question step-by-step.

### Part a) Fill in the population of the table to the nearest 1000

We need to round each population figure to the nearest thousand.

1. Cuba
- Population: 11,238,317
- Rounded to the nearest 1000: 11,238,000

2. Dominican Republic
- Population: 9,980,243
- Rounded to the nearest 1000: 9,980,000

3. Guadeloupe
- Population: 403,314
- Rounded to the nearest 1000: 403,000

4. Haiti
- Population: 10,745,665
- Rounded to the nearest 1000: 10,746,000

5. Jamaica
- Population: 2,717,991
- Rounded to the nearest 1000: 2,718,000

6. Puerto Rico
- Population: 3,548,397
- Rounded to the nearest 1000: 3,548,000

7. Trinidad and Tobago
- Population: 1,328,019
- Rounded to the nearest 1000: 1,328,000

This information is filled into the table as follows:

[tex]\[ \begin{tabular}{|l|c|c|c|} \hline Island & Population & \begin{tabular}{c} Population to \\ nearest 1000 \end{tabular} & \begin{tabular}{c} Order (1=smallest \\ 7=largest) \end{tabular} \\ \hline Cuba & 11,238,317 & 11,238,000 & 7 \\ \hline Dominican Republic & 9,980,243 & 9,980,000 & 5 \\ \hline Guadeloupe & 403,314 & 403,000 & 1 \\ \hline Haiti & 10,745,665 & 10,746,000 & 6 \\ \hline Jamaica & 2,717,991 & 2,718,000 & 3 \\ \hline Puerto Rico & 3,548,397 & 3,548,000 & 4 \\ \hline Trinidad and Tobago & 1,328,019 & 1,328,000 & 2 \\ \hline \end{tabular} \][/tex]

### Part b) Write the population in ascending order

Sorting the populations rounded to the nearest 1000 in ascending order:

- Guadeloupe: 403,000
- Trinidad and Tobago: 1,328,000
- Jamaica: 2,718,000
- Puerto Rico: 3,548,000
- Dominican Republic: 9,980,000
- Haiti: 10,746,000
- Cuba: 11,238,000

So, the order from smallest to largest population is:

1. Guadeloupe: 403,000
2. Trinidad and Tobago: 1,328,000
3. Jamaica: 2,718,000
4. Puerto Rico: 3,548,000
5. Dominican Republic: 9,980,000
6. Haiti: 10,746,000
7. Cuba: 11,238,000

### Part 6. Change in value when interchanging digits of 9372

We need to interchange the thousands and the tens digit of the number 9372 and determine the change in its value.

- Original number: 9372
- Thousands digit: 9
- Tens digit: 7

By interchanging these digits, the new number becomes 7392.

The change in value is calculated as:
[tex]\[ 9372 - 7392 = 1980 \][/tex]

Thus, the value of the number changes by 1980.

### Summary:
- a) Populations rounded to the nearest 1000:
- Cuba: 11,238,000
- Dominican Republic: 9,980,000
- Guadeloupe: 403,000
- Haiti: 10,746,000
- Jamaica: 2,718,000
- Puerto Rico: 3,548,000
- Trinidad and Tobago: 1,328,000
- b) Populations in ascending order:
1. Guadeloupe: 403,000
2. Trinidad and Tobago: 1,328,000
3. Jamaica: 2,718,000
4. Puerto Rico: 3,548,000
5. Dominican Republic: 9,980,000
6. Haiti: 10,746,000
7. Cuba: 11,238,000
- Change in value when interchanging digits of 9372: 1980
