A study was conducted to compare to brands of milk. Random sample A of 25 packs of milk with a mean content of 237 grams and standard deviation of 8.56 grams. Another sample B of 20 packs of milk showed a mean content of 240 grams and standard deviation of 9.75 grams. Using 0.05 level of significance will we agree that sample A exceeds that of sample B by 2 grams nutrient content, conduct hypothesis testing assuming that variances are equal.
