Question

The American Veterinary Medical Association believes that half of veterinary clinics do not treat large animals (cows, horses, etc.). The American Veterinary Medical Association conducted a survey of veterinary clinics to estimate the proportion that do not treat large animals (cows, horses, etc.). In the survey of 120 randomly selected veterinary clinics throughout the country, 88 responded they do not treat large animals. The test statistic for the above hypothesis test about the proportion of clinics that do not treat large animals is... (Round your answer to two decimal places)

Answer 1

Percentage = 88/120 × 100 ≈ 73.33 %

Answer 2

The test statistic for the above hypothesis test about the proportion of clinics that do not treat large animals is wrongly estimated

Explanation:

This is a simple distribution principle used in testing. There are only two variables and we are given the total number of observations in the test.

Total observations = 120

Number of clinics who did not treat large animals = 88

Number of clinics that would operate large animals = 120 - 88 = 32

Percentage of clinics that do not treat large animals = (88 / 120) x 100

Percentage of clinics that do not treat large animals = 73%

Since 73% is significantly large than 50% in hypothesis, hence it is not accurate
