A playground has a fence covering an area with the coordinates of A(2, 3), B(-3, 2), and C(2, -2). The park wants to extend the fence's range by a scale factor of 2. PLZ I WILL GIVE BRAINLIEST ANSWER

a) Increase the sample size

Step-by-step explanation:

Given that a 95%  confidence interval for μ turns out to be (1,000, 2,100)

The confidence interval is formed as

Margin of error = critical value * std dev/sqrt of sample size

Hence for the same confidence level, we cannot change critical value.

The only available ways are either to decrease std deviation or increase the sample size to make it narrower.

If confidence level becomes higher, then confidence interval would be wider.

Here  out of four options the correct option is

a) Increase the sample size
