Answer

The table is attached.

Work Step by Step

We are asked to find the expected number of responses for a different sample size. To do this, we multiply each number in the table by the new number of samples divided by the old number of samples. For instance, since 500 adults said that they hate public speaking in the 1000 person survey, in the 10,000 person survey, we expect the new number of responses to be: $$ = \frac{10,000}{1,000} \cdot 500 =5000$$
