In a survey of 120 publicly-traded companies, the average price-earnings ratio was 18.5 with a standard deviation of 8.2. When testing the hypothesis (at the [a]% level of significance) that the average energy use has decreased from the past value of 16.8, the p-value is 0.0116. Therefore, if you are using a 10% level of significance that the average price-earnings ratio has decreased from the past, what is your conclusion concerning the null hypothesis?
