Recаll:A mаnufаcturing engineer is evaluating whether a prоcess adjustment has reduced variability in the оutput vоltage of a precision electronic component used in a control system.From historical process records, the population standard deviation of the output voltage is known to be: σ = 0.50 volts.A random sample of 15 components from the adjusted process produced a sample standard deviation of s = 0.35 volts.Original process: n1=15, x¯1=12.40 volts, s1=0.45 voltsAdjusted process: n2=15, x2=12.25 volts, s2=0.35 voltsThe engineer wants a 95% confidence interval for the population standard deviation of the adjusted process.Reference Values (Provided — No Tables Needed)z0.975=1.96t*0.975,14=2.145χ14,0.0252=26.12χ214,0.975=5.63Which of the following is the correct 95% confidence interval for the population standard deviation σ of the adjusted process? Note: when performing calculations, use 4 decimal places.
