Two types of candles are tested for their burning times (in min) and the sample results are listed in the table below. Does the Brand A candle have the same average burning time as Brand B? Assuming the equal variance. The calculated t statistics is 4.11. Significance level = 0.01 BRAND A n1=16 =19.4 S1=1.4 BRAND B n2=10 =17.2 S2=1.2 1. What is the null hypothesis for this question? Answer H0: Solution 1. What is the null hypothesis for this question? Answer : H0: µA = µB.
