Find the interval [ μ-zσn√,μ+zσn√ ] within which 95 percent of the sample means would be expected to fall, assuming that each sample is from a normal population. (a) μ = 196, σ = 14, n = 33. (Round your answers to 2 decimal places.) The 95% range is from to. (b) μ = 1,430, σ = 25, n = 9. (Round your answers to 2 decimal places.) The 95% range is from to. (c) μ = 48, σ = 1, n = 25. (Round your answers to 3 decimal places.) The 95% range is from to.
