Let's just first find what this value should be. We have 2.064 standard errors
below 1700. So this should be 1700 minus 2.064 standard errors, which is 200
divided by the square root of 25. This calculates to $1,617.44. And then we'll
do the same thing with this value on the right of 1700. We have 1700 plus 2.064
standard errors, and this comes out to $1,782.56. And there we have our 95%
confidence interval.
