A biologisst reports a confidence interval of (3,7,5,5) when estimating the mean height ( incentimeters)
Of a sample of seedlings.
The estimated margin of errors is___
To calculate the estimated margin of error, you need to find the range of the confidence interval.
In this case, the range of the confidence interval is the difference between the upper limit and the lower limit.
The upper limit is 7.5 cm and the lower limit is 3.5 cm.
So, the estimated margin of error is:
7.5 cm - 3.5 cm = 4 cm.
Therefore, the estimated margin of error is 4 cm.
