For a particular production facility, the total milk yield per goat (for a 10-month lactation period) has averaged 1180 pounds. In an experiment, 14 goats were randomly selected from the facility and, in addition to their regular diet, they were fed a supplement of crude protein, which is thought to affect milk yield. In the experiment, the yields for these 14 goats were: 1209 1358 1380 1098 1241 1325 1008 1217 1487 1217 1269 1348 1139 1122.Suppose that the milk volumes among all goats are NOT known to be normally distributed and that the variance was unknown. Find the p-value and interpret it. The conclusions change? State the assumptions that you had to make in order to answer this question.
