Question

In a trial of 125 patients who received 10-mg doses of a drug daily, 30 reported a headache as a side effect Use the information above to complete parts (a) through (c) a. Verity that the requirements for constructing a confidence interval about p are satisfied Are the requirements for constructing a confidence interval about p satisfied? O Yes O No b. Construct a 90 % confidence interval for the population proportion of drug users who will report a headache as a side effect The confidence interval is fromto (Use ascending order. Round to three decimal places as needed) c. Interpret the confidence interval Choose the correct answer below OA There is a 90% chance that the true value of p will fall in the interval OC. There is a 90% chance that the true value of p will not fall in the interval OB. We are 90% contident that the interval actualy does contain the tru O D. We are 90% contident that the interval actually does not contain ther

Answer 1

Tos nos efficiently lounge 90% CI = P + NORMS INV (0,05) TP ci-f) Excelbu? NORMS INV (0.05) = 1.645 ſ = 3= 0.24 ; n=125 125 = 0.24 £ 1.645 | 0.24 x 0.76 125 = 0.24 + 0.063 - 10.177] < p <0.303 | We are 50% Confident ....
