Answer:

x^2 = 22.99

Step-by-step explanation:

Given data:

standard deviation of all filled bottles = 0.1

overall hypothesis is significant at $\sigma = 0.1$

for test statistics, use chi-square test

$x^2 = \frac{(n-1) s^2}{\sigma^2}$

where

n - sample size

s =simple deviation

$x^2 =\frac{(20-1)0.011^2}{0.1^2}$

$x^2 = 22.99$
