10.	A simple random sample of size 17 has mean x̄ = 8.44 and standard deviation s = 5.38. The population is normally distributed. Construct a 95% confidence interval for the population standard deviation

Answer 1

given that

sample size =n=17

sample mean=m=8.44

sample SD=S=5.38

since in the question we have to calculate the confidence interval for standard deviation hence

here we are estimating population standard deviation

since we know that % confidence interval for SD is given by

where is upper chi square value with df of chi square=n-1

as we have to find 95% confidence interval then

here n=17 so DF=n-1=17-1=16

from chi square table with df=16 we get the values

so 95% confidence interval is given by
