A senior-level manufacturing engineer wants to verify the software results provided by his team evaluating whether a surface‑finishing process has altered the mean thickness of a protective coating before including them in a formal process‑change report. Here are the details: Target (historical) mean thickness: μ₀ = 125 microns A random sample of 12 components is collected after the process change. The engineer performs a two‑tailed one‑sample t‑test using statistical software. Using the data and software output below, complete the following checks.

Recall:A manufacturing engineer is evaluating whether a process adjustment has reduced variability in the output voltage 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?

A manufacturing engineer is evaluating whether a process adjustment has reduced variability in the output voltage of a precision electronic component used in a control system. Excessive voltage fluctuation has previously caused downstream calibration issues.From historical process records, the population standard deviation of the output voltage is known to be: σ = 0.50 volts.After implementing the adjustment, the engineer collects a random sample of 15 components from the adjusted process and measures their output voltage. The sample produces a sample standard deviation of s = 0.35 volts.In addition to assessing variability, the engineer wants to determine whether the process adjustment has affected the mean output voltage. To do this, independent samples are collected from both the original and adjusted processes:Original process:n1=15, x¯1=12.40 volts, s1=0.45 voltsAdjusted process:n2=15, x2=12.25 volts, s2=0.35 voltsAssume the samples are independent.What parameter is being estimated when evaluating variability after the process adjustment?
