Question

A chemical engineer has been working on developing a new type of candle wax made from coconut oil. The engineer wonders how the amount of time that a candle made of coconut oil wax will burn compared to the time that a candle made of beeswax will burn.

After gathering the appropriate data and ensuring that the necessary conditions have been satisfied, which type of significance test should the engineer conduct?

Answer 1

The engineer will conduct "two-sample t-test for the difference in population mean".

The two-sample t-test is used to test the difference (d0) between two population means. A common application is to determine whether the means are equal.
