- In 1986 a catastrophic nuclear accident in the Ukraniancity of Chernobyl exposed the surrounding area to largeamounts of radiation. Since then, scientists have beeninvestigating the aftereffects on plants, animals, andhumans. A 2007 study examined 841 barn swallowsthere, noting the incidence of deformed toes and beaks, abnormal tail feathers, deformed eyes, tumors, and albi-nism (a condition that involves discoloration of the birds’ plumage). Previous studies involving thousands of barn swallows in Spain, Italy, and Denmark had seen albi-nism in 4.35% of this species, yet 112 of the Chernobyl swallows displayed the condition.a) Is there evidence that the albinism rate is higheramong Chernobyl barn swallows? b) What does this study tell us about the effect of nu-clear contamination on barn swallows?4. C-Spec, Inc., is attempting to determine whether an existing machine is capable of milling an engine part that has a key specification of 4 ± 0.003 inches. After a trial run on this machine, C-Spec has determined that the machine has a sample mean of 4.001 inches with a standard deviation of 0.002 inch. a. Calculate the capability ratio for this machine. b. Calculate the capability index for this machine c. Should C-Spec use this machine to produce this part? d. Explain why? e.
