Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence interval of left parenthesis 1.9 comma 3.3 right parenthesis when estimating the mean height (in centimeters) of a sample of seedlings. The estimated margin of error is nothing . The sample mean is nothing .

And the margin of error with this one:

Step-by-step explanation:

Assuming that the parameter of interest is the sample mean . And we can estimate this parameter with a confidence interval given by this formula:

  (1)

For this case the confidence interval is given by (1.9, 3.3)

Since the confidence interval is symmetrical we can estimate the sample mean with this formula:

And the margin of error with this one:

it would rotate about 180 degrees.
