Researchers studied the mean egg length (in millimeters) for a bird population. after taking a random sample of eggs, they obtained a 95% confidence interval of (45,60). what is the value of the margin of error?

The margin of error is 7.5

Explanation:

Since we know that the interval is of the form MOEx±, we have that 45 = MOEx−and 60 = MOEx+.by solving this system of equations, we find that MOE = 7.5

an aneroid barometer is different from a mercury barometer in that it provides readings that increase as air pressure increases.
