A biologist reports a confidence interval of (3.1, 4.5) when estimating the mean height (in centimeters) of a sample of seedlings.
The estimated margin of error is?
2*ME = (4.5-3.1)
ME = 1.4/2 = 0.7
============================
The sample mean is?
sample mean = (4.5+3.1)/2 = 7.6/2 = 3.8
==========================================
