Answer:
x^2 = 22.99
Step-by-step explanation:
Given data:
standard deviation of all filled bottles = 0.1
overall hypothesis is significant at[tex] \sigma = 0.1[/tex]
for test statistics, use chi-square test
[tex]x^2 = \frac{(n-1) s^2}{\sigma^2}[/tex]
where
n - sample size
s =simple deviation
[tex]x^2 =\frac{(20-1)0.011^2}{0.1^2}[/tex]
[tex]x^2 = 22.99[/tex]
