A process has been developed that can transform ordinary iron into a kind of super iron called metallic glass. Metallic glass is

three to four times stronger than the toughest steel alloys. To estimate the mean temperature, μ, at which a particular type of metallic glass becomes brittle, 25 pieces of this metallic glass were randomly sampled from a recent production run. Each piece was subjected to higher and higher temperatures until it became brittle. The temperature at which brittleness first appeared was recorded for each piece in the sample. The following results were obtained: x = 480°F and s = 1 10F. Construct a 95% confidence interval to estimate Lu
