1. In a trial of 123 patients who received 10-mg doses of a drug daily, 32 reported headache as a side effect. Use this information to complete parts (a) through (d) below.(a) Obtain a point estimate for the population proportion of patients who received 10-mg doses of a drug daily and reported headache as a side effect.(b) Verify that the requirements for constructing a confidence interval about p are satisfie(c) Construct a 99 % confidence interval for the population proportion of patients who receive the drug and report headache as a side effect.d) Interpret the confidence interval.2)In a poll, 416 of 1040 randomly selected adults aged 18 or older stated that they believe there is too little spending on national defense. Use this information to complete parts (a) through (e) below.(a) Obtain a point estimate for the proportion of adults aged 18 or older who feel there is too little spending on national defense. ModifyingAbove p with caretpequals=0.40.4 (Simplify your answer.) (b) Verify that the requirements for constructing a confidence interval about p are satisfied. Are the requirements for constructing a confidence interval about p satisfied? A. Yes, the requirements for constructing a confidence interval are satisfied.Your answer is correct. B. No, the requirement that n ModifyingAbove p with caret left parenthesis 1 minus ModifyingAbove p with caret right parenthesisnp1?p is greater than 10 is not satisfied. C. No, the requirement that the sample size is no more than 5% of the population is not satisfied. D. No, the requirement that the sample be a simple random sample is not satisfied. (c) Construct a 9999 % confidence interval for the proportion of adults aged 18 or older who believe there is too little spending on national defense.The 99 % confidence interval is ( ? , ? ). (Round to three decimal places as needed.)3. A simple random sample of size n is drawn. The sample mean, x, is found to be 18.1 , and the sample standard deviation is found to be 4.6.LOADING… Click the icon to view the table of areas under the t-distribution.(c) Construct a 99 % confidence interval about ? A poll was conducted that asked 10071007 people how many books they had read in the past year. Results indicated that x overbarxequals=13.413.4 books and sequals=16.616.6 books. Construct a 9090 % confidence interval for the mean number of books people read. LOADING… Click the icon to view the table of areas under the t-distribution.Construct a 9090 % confidence interval for the mean number of books people read. (? ,? )Based on interviews with 9595 SARS patients, researchers found that the mean incubation period was 4.84.8 days, with a standard deviation of 14.314.3 days. Based on this information, construct a 95% confidence interval for the mean incubation period of the SARS virus. Interpret the interval.The lower/upper bound is ?.
