A complete sentence that includes the confidence level explaining your result in context. For Hypothesis Tests you must include the 4 steps: Hypothesize (write the null and alternative hypotheses using correct notation) Prepare: Indicate the significance level a (usually given) and ensure that the conditions for testing are met. Show calculations where necessary. Compute: Calculate the test statistic and p-value. Include a sketch with the test statistic marked and the p-value shaded. Indicate what was entered into StatCrunch to get these results. Interpret: Write a complete sentence explaining your conclusion in context
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 180 veterinary clinics throughout the country and of these, 137 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. [4 points] 3. ) orts

Answers

Solution:-

3) 95% confidence interval for the proportion of all vet clinics that do not treat large animals is C.I = ( 0.6988, 0.8234).

Point estimate = 137/180 = 0.7611

Margin or error = 0.0623

C.I pt2a/2x 1/P(1-p)

C.I = 0.76111 + 1.96 × 0.03178

C.I = 0.76111 + 0.06229

C.I = ( 0.6988, 0.8234)

95% confidence interval for the proportion of all vet clinics that do not treat large animals is C.I = ( 0.6988, 0.8234).
