Answer:c
Step-by-step explanation:
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
