Anestetic [448]

Answer:

3.113, 4.507

Step-by-step explanation:

From the given values:

Mean = 3.81

Standard deviation = 1.74

Therefore

M = √(1.72/18) = 0.4

μ = M ± t(sM)

μ = 3.81 ± 1.74*0.4

μ = 3.81 ± 0.697

Recall that the mean is estimated at 90% confidence level,

Hence,

= 90% CI [3.113, 4.507]
