Before constructing the condence interval using a normal approximation to the binomial distribution, rst check that me? :- 5 and mi 3. 5, INhere n is the number of judges in the sample, 51?, 35 was previouslyr computed to be P = 11.5416, and ti = 1 ,. Compute no and no, rounding the results to the nearest Iwhole number. n, = Elia-541m = E m? = E u mm: = : Because the criteria :15 :2, 5 and m; :2, 5 met, we continue Iwith the condence interval for ,o. Five hundred twelve (512) homes in a certain southern California community are randomly surveyed to determine if they meet minimal earthquake preparedness recommendations. One hundred seventy-one (171) of the homes surveyed met the minimum recommendations for earthquake preparedness and 341 did not. Find the confidence interval at the 90% confidence level for the true population proportion of southern California community homes meeting at least the minimum recommendations for earthquake preparedness. (Round your answers to three decimal places.) .308 X .360 xA random sample of 334 medical doctors showed that 170 had a solo practice. LA USE SALT (a) Let p represent the proportion of all medical doctors who have a solo practice. Find a point estimate for p. (Use 3 decimal places.) (b) Find a 98% confidence interval for p. (Use 3 decimal places.) lower limit upper limit Give a brief explanation of the meaning of the interval. O 2% of the all confidence intervals would include the true proportion of physicians with solo practices. O 98% of the all confidence intervals would include the true proportion of physicians with solo practices. O 98% of the confidence intervals created using this method would include the true proportion of physicians with solo practices. 2% of the confidence intervals created using this method would include the true proportion of physicians with solo practices. (c) As a news writer, how would you report the survey results regarding the percentage of medical doctors in solo practice? O Report p. O Report p along with the margin of error. O Report the confidence interval. O Report the margin of error. What is the margin of error based on a 98% confidence interval? (Use 3 decimal places.)
