critical measurement influenced by these machines is the weight of the product

Two different box-filling machines are used on an assembly line. The critical measurement influenced by these machines is the weight of the product in the boxes. Engineers are quite certain that the variance of the weight of product is o" = 5 ounces. Experiments are conducted using both machines with sample sizes of 36 each. The sample averages for machines A and B are XA = 24.2 ounces and Xp = 24.4 ounces. Engineers are surprised that the two sample averages for the filling machines are so different. Complete parts (a) and (b) below. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. (a) Use the Central Limit Theorem to determine P(Xp - XA 2 0.2) under the condition that HA = HB- P( X B - XA = 0.2 ) =[
