It is given that is the sample proportion of entrepreneurs whose first startup was at 30 years or more is

The sampling distribution of the proportion is approximately normal if

Verify the conditions:

And

The conditions are satisfied. Therefore, the sampling distribution of the proportion is normal.

The mean of the

Mean and standard deviation are calculated as below

Thus, the sampling distribution of the proportion J of entrepreneurs whose first startup was at 30 years or more is normal with mean
