Construct a 90% confidence interval to estimate the mean boiling temperature of the substance. State values to one decimal place.

Write a sentence to interpret the confidence interval constructed in part (a) in the context of the problem statement. Use the guidelines established in class.
The metallurgist suspected that the substance is Scandium. Scandium has a boiling temperature of 3109 K. Does the confidence interval give evidence to support the metallurgist preliminary identification? BRIEFLY explain using the confidence interval.
