Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! use the confidence interval to find the margin of error and the sample mean.a biologist reports a confidence interval of(1.8,2.4)when estimating the mean height(in centimeters)of a sample of seedlings.
the sample mean is the middle, or average, of the interval: (1.8+2.4)/2 = 1.56
----------
the estimated margin of error is (1/2) the width of the interval: 0.6/2 = 0.3
