Answer: Interval would be (0.29,0.58).
Step-by-step explanation:
Since we have given
n = Sample size = 54
Variance = 0.44
we need to find 98% confidence interval to estimate the variance.
So, we will use "Chi square distribution"
For this , we will find
df = n-1=54-1=53
Interval would be


similarly,

So, it becomes,

Hence, interval would be (0.29,0.58).
