I need help solving this please. It’s a statistics question
The breaking strength of yarn used in the production of woven carpet material is normally distributed with standard deviation 2.4 psi. A random sample of 4 specimens of yarn from a production run is measured for breaking strength, and a confidence interval for is calculated to be (128.609,134.191). What is the confidence level for this interval?
(А) 0.90
(B) 0.95
(C) 0.96
(D) 0.98
(E) 0.99
