Use the one-standard-deviation chi-square interval procedure to obtain the specified confidence interval for thepopulation standard deviation Ϭ. Assume that the population has a normal distribution.
-The weights of 14 men selected at random from one town have a mean, $\overline { x _ { t } }$ , of 159.3 lb and a standard deviation, s, of 13.5 lb. Determine a 90% confidence interval for the standard deviation, Ϭ, of the
Weights of all men from this town.
A)10.6 to 17.4 lb
B)10.3 to 20.0 lb
C)10.9 to 2.7 lb
D)10.0 to 19.0 lb
