Question
1. Consider the data in Ex. 7.76. Do the data provide significant evidence, at the 4.2% level, to indicate that the population proportion of Italian dairy farms that carry out dehorning is greater than 0.80? (Do this instead of what the exercise in the book asks.) 7.76 Dehorning of dairy calves. For safety reasons, calf dehorn- ing has become a routine practice at dairy farms. A report by Europe's Standing Committee on the Food Chain and Animal Health (SANKO) stated that 80% of European dairy farms carry out calf dehorning. A later study, published in the Journal of Dairy Science (Vol. 94, 2011), found that in a sample of 639 Italian dairy farms, 515 dehorned calves. Does the Journal of Dairy Science study support or refute the fig- ure reported by SANKO? Explain. Support, z = .38
