The crowd that heard the President speak was estimated to be 10,000 peoples. The actual crowd could be 750 people more or less than this. What are the possible values for the actual crowd size?

what's 750 less than 10,000?

what's 750 more than 10,000?

That's your answer . . .

To determine the possible values for the actual crowd size, we need to consider the estimated crowd size of 10,000 and the margin of error of 750 people on either side.

To calculate the higher bound, we add the margin of error to the estimated crowd size:
10,000 + 750 = 10,750.

Therefore, the highest possible value for the actual crowd size is 10,750.

To calculate the lower bound, we subtract the margin of error from the estimated crowd size:
10,000 - 750 = 9,250.

Therefore, the lowest possible value for the actual crowd size is 9,250.

In conclusion, the possible values for the actual crowd size range from 9,250 to 10,750 people.
