andle company wishes to estimate the time it takes their candles to completely burn. They choose 18 candles at random from their latest production run and measure how long each takes to burn. The average time of this sample is 250 minutes and the standard deviation of this sample is 21 minutes. If the company uses a 99% confidence interval to measure the average burn time of all candles in this production run, what will their margin of error be?
