A manufacturer of sprinklers for fire protection in buildings claims that the true average system activation temperature is 130 degrees. Given that the population is normal and testing 9 sprinklers, you find a sample average temperature of 131.08 degrees with a standard deviation = 1.5 degrees. At the significance level of α=0.01, what is your conclusion about the hypothesis test you developed to determine if the actual average is 130 degrees?
