Use the confidence level and Sample data to find the margin of error E. Round your answer to the same number of decimal places a
Ivenika [448]

Answer:

A) 2.6 mm Hg

Step-by-step explanation:

Margin of error = critical value × standard error

ME = CV × SE

n > 30, so we can approximate CV with a normal distribution.  At P = 94%, CV = 1.88.

SE = σ / √n

SE = 13.5 / √92

SE = 1.41

So the margin of error is:

ME = 1.88 × 1.41

ME = 2.6
