Practice question #2 The melting point of each of 31 samples of a certain brand of hydrogenated vegetable oil was determined, resulting in a sample mean of 95.5 degrees and a sample standard deviation of 1.9. Construct a 99% confidence interval for the melting point of this brand of hydrogenated vegetable oil. Write out your formula and verify size is appropriate for this method. Round answers to 1 decimal place. Verify size is appropriate for method: Interval: Interpret the interval in the context of the problem: If we had instead calculated a 95% confidence interval, would the interval have been wider or narrower? You do not have to calculate it.
