New Chicken Feed: When a poultry farmer uses her regular feed, the newborn chickens haye normally distributed weights with a mean of 62.2 ounces. In an experiment with an enriched feed mixture, nine chickens are bom with the weights {in ounces}: 61.4 65.2 66.? 63.3 66.2 66.0 63.5 63.? 66.6 PART 1 Questions: a} Compute the sample mean. sample standard deviation, median, IQR [2 decimal places} for the weights of newborn chickens using the enriched feed mixture. Include the units in your answer b} Compute the 95% condence interval for the population mean weight of the newborn chickens in this farmer's poultry. Round to 2 decimal places and write the answer in the format: lower boundary s u s upper boundary. Do not interpret. PART 2 |Question: Perform a hypothesis test to answer the question: Use a 5% signicance leyel to test the claim that the mean weight of chickens with the enriched feed mixture is different than the regular feed. mmsmmmmmehmmm: a} State Ho and H1 in symbols and in words. Identify which hypothesis is the claim. type of test {righttoil, lefttoil, two toil]. h] Determine the critical value and label it. For example. a = 1.9!!! ort = -2.421, etc. c] Compute the test value, 2 or t. If you are using the p'yalue method. then compute the test yalue and p-yalue of the test. d} Make the decision to Reject Ho or Do not reject Ho. e} State your complete conclusion in the context of the claim
