A seniоr-level mаnufаcturing engineer wаnts tо verify the sоftware 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. Software Output One-Sample T: Coating Thickness Test of mu = 125 vs not = 125 Variable N Mean StDev SE Mean 95% CI T-Value DF P-Value Thickness 12 126.7 3.1 ? (125.8, 131.0) ? 11 0.015 Tasks (a) Compute the standard error (SE) of the sample mean. SE Mean=[BLANK-1] (b) Compute the t‑statistic. T-value=[BLANK-2] (c) Based on your calculations and the reported P‑value, what is the best conclusion? Reject, Accept, or Fail to Reject? [BLANK-3] Note: Round your answers to 2 decimal places
