A study of generationrelated carbon monoxide deaths showed that a random sample of 6 recent years had a standard deviation of 4.1 deaths per year. Find the 99% confidence interval of the variance and standard deviation. Assume the variable is normally distributed.
Homework Answers
100(1-
) % confidence
interval for variance :
We are given
n = 6
s = 4.1
= 1 - 0.99 =
0.01
99 % confidence interval for variance :
Now,
100(1-) % confidence
interval for Standard deviation :
So,
