The desired statistical measures are given as follows:
1. The margin of error is of .
2. The margin of error is of 0.02 = 2%.
3. The point estimate is of 0.655.
<h3>What is the margin of error when we are given the sample standard deviation?</h3>We also have to be given the sample size n, along with the standard deviation s, and the margin of error is given by:
In item 1, we have that s = 6.75, hence the margin of error is:
The margin of error is given by half the subtraction of the bounds, hence, for item 2:
(0.37 - 0.33)/2 = 0.02.
The margin of error is of 0.02 = 2%.
<h3>What is the point estimate of an interval when we are given two bounds of an interval?</h3>The points estimate is given by the mean of the bounds, hence, for item 3:
M = (0.61 + 0.70)/2 = 0.655.
The point estimate is of 0.655.
