The diameter of cork of a Champagne bottle is supposed to be 1.5
cm. If the cork is either too large or too small, it will not fit
in the bottle. The random sample data shows strong
evidence that the true mean diameter
has moved away from the target, at
significance level α = 0.01. Which of the following intervals could
be the 99% confidence interval of the true mean based on this
sample?
(1.343cm, 1.521cm)
(1.458cm, 1.499cm)
(1.488cm, 1.501cm)
(1.343cm, 1.521cm)
(1.498cm, 1.604cm)
