The weights of the watermelons grown on a farm are normally distributed. The mean weight has been μ0=32.5 pounds. Because of the use of a new fertilizer, the farmer would like to know if the mean weight has changed. A random sample of n=9 watermelons is selected. The sample mean is x=33.8 pounds and the sample standard deviation is s=2.45 pounds. Test if the population mean has changed at a significance level a=0.05.
