Question

A random sample of 10 pigs fed on diet A, the increase in weight in pounds in certain period were x: 10, 6, 16, 17, 13, 12, 8, 14, 15, 9. Another sample of 12 pigs fed on diet B,the increase in weight in pounds in certain period were y: 7, 13, 22, 15, 12, 14, 18, 8, 21, 23, 10, 17.

Answer 1

Answer:

Step-by-step explanation:

For a random sample of 10 persons , fed on diet A, the increased in weight in Kgs for a certain period were: 10, 6,16,17, 13, 12, 8 14,15,9 (mean= 13.4; SE= 1.634) Test whether the gain in weight, on an average is 15.0 Kgs. Ho = Sample mean is not different from population mean (15.0) or mean gain in weight = 15.0 kgs. H1 = Sample mean is different from population mean (¹ 15.0) or Mean gain in weight ¹ 15.0 kgs t = (Sample mean – Population mean)/ SE of mean = ( 13.4-15.0)/1.634 = - 0.979 (df = 9) = P=0.35 or P > 0.05 Hence, Ho is accepted => the sample mean = 15.0
