Answer 1

By averaging the interval's bottom and upper bounds, one can get the point estimate, which is the middle of the confidence interval.
The point estimate's formula is as follows:
Lower Bound + Upper Bound = Point Estimate


Changing the specified values:
Point Estimate: 50644 + 49078

The difference between the point estimate and either end of the confidence interval is known as the margin of error.
The margin of error is calculated as follows:
Point Estimate - Upper Bound = Margin of Error
Changing the values:
Error Margin = 50644 - Point Estimation
Let's figure out these numbers.
