Use the confidence level and sample data to find a confidence interval for estimating the population mu. Round your answer to th

inysia [295]

Answer:

c. 9.5 lb < mu < 11.1 lb.

Step-by-step explanation:

Confidence interval can be stated as M±ME where

M is the sample mean (10.3)
ME is the margin of error

margin of error (ME) around the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in 95% confidence level (1.96)

s is the standard deviation of the sample (2.4)

N is the sample size (37)

Putting thesenumbers in the formula we get:

ME= $\frac{1.96*2.4}{\sqrt{37} }$ ≈ 0.7733 ≈ 0.8

Then the 95% confidence interval would be 10.3 ± 0.8
