7910/14 long division below
Step-by-step explanation:
Given precision is a standard deviation of s=1.8, n=12, target precision is a standard deviation of σ=1.2
The test hypothesis is
H_o:σ <=1.2
Ha:σ > 1.2
The test statistic is
chi square = ![\frac{(n-1)s^2}{\sigma^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%28n-1%29s%5E2%7D%7B%5Csigma%5E2%7D)
=![\frac{(12-1)1.8^2}{1.2^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%2812-1%291.8%5E2%7D%7B1.2%5E2%7D)
=24.75
Given a=0.01, the critical value is chi square(with a=0.01, d_f=n-1=11)= 3.05 (check chi square table)
Since 24.75 > 3.05, we reject H_o.
So, we can conclude that her standard deviation is greater than the target.
