Question

The American Veterinary Medical Association (AMVA) conducted a survey of veterinary clinics to estimate the proportion that do not treat large animals (cows, horses, etc.). The survey was mailed to a random sample of 194 veterinary clinics throughout the country and of these, 148 responded that they do not treat large animals. Give a 95% confidence interval for the proportion of all vet clinics that do not treat large animals.

  1. Verify the conditions for the Central Limit Theorem (and thus for calculating a Confidence Interval for a proportion) are satisfied.

Random independent sample= given

Big population 

194(.76)=147.4

194(1-.76)=46.56

Over 10?  Yes

 

  1. State the estimate from the sample

 

  1. State the margin of error

 

  1. Write a sentence explaining your result in context
