Answer: 
Step-by-step explanation:
Given : sample size : n= 51
sample standard deviation : s= 0.46
Significance level : 
Using chi-square distribution, the critical values will be :


Confidence interval for population standard deviation (
) :

Substitute all the values , we get

Hence, the 95% two-sided confidence interval for σ : 
Answer:
x=5,1
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
I have no idea I’m answering this because I need to ask more questions
117/3 = 39
39 + 39 + 39 = 177
They must be consecutive.
The integers are 37, 39, and 41.
