In a trial of 100 patients who received 10-mg doses of a drug dally, 36 reponed headache as a side effect. Use this information to complete parts (a) through (a) 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. D-(Round to two decimal places as needed.) (b) Verity that the requirements for constructing a confidence interval about p are satisfied Are the...
2. If a sample of n = 49 was obtained a = 260, S = 6. Try the following hypothesis: Use a = 0.10 * Is there evidence that the average mx is greater than 247? * Estimate a confidence interval of 90% for the true value of the average of this population. * Determine β and the power of the test. (1-β) of the previous hypothesis * Determine the p-value for the previous test.
Y~Bin(n,p). 15 of 100 samples are successes. Test the null hypothesis H0 : p = 0.10 against the alternative Ha : p > 0.10 at level alpha = 0.1 Find the p value.
Please help, thanks MC 1) Assume that the 99% confidence interval for a regression slope parameter β2 is from -0.3 to 0.8, while the 95% confidence interval for is from 0.1 to 0.4. Suppose you are interested in a test of the null hypothesis Ho : β2--O against the alternative of H1 : β2 Which of the following staternents is true about the p-value for this test? a) p-value >0.05 99 % b) p-value >0.10 fol to ret at ll...
Test H0: π = 0.25 versus HA: π ¹ 0.25 with p = 0.33 and n = 100 at alpha = 0.05 and 0.10.
2. Basic Computation: Confidence Interval for p Consider n = 200 binomial trials with r = 80 successes. Check Requirements Is it appropriate to use a normal distribution to approximate the p̂ distribution? Find a 95% confidence interval for the population proportion of successes p. Interpretation Explain the meaning of the confidence interval you computed. 3. Basic Computation: Sample Size What is the minimal sample size needed for a 95% confidence interval to have a maximal margin of error of...
- Suppose that the binomial distribution parameter a is to be estimated by P = X/n, where X is the number of successes in n independent trials, i.e. P is the sample proportion of successes. i. Write down the endpoints of an approximate 100(1 – a)% confidence interval for at, stating any necessary conditions which should be satisfied for such an approximate confidence interval to be used. You should also state the approximate sampling distribution of P = X/n. ii....
A (1-alpha)*100% confidence interval for population mean Mu can also be used to test a hypothesis about Mu? 1. True 2. False
Use the following information for the next five questions: Let the random variable p indicate the population proportion of US households who are dog owners. In a sample of 100 households you find the sample proportion of families who own dogs to be =0.40 Construct a 95% confidence interval for , the true proportion of households who own a dog. [.319 , .481] [.304 , .496] [.312 , .492] [.395 , .405] Use the following information along with the information above...
step 2: find the margin of error used in constructing the confidence interval. round your answer to six decimal place. step 3 construct 99% confidence intervel. round to 6 decimal place Step 2 find the critical value in constructing confidence intervel. step 3 find the standard deviation Step 4construct 90% confidence interval Given two independent random samples with the following results: N = 16 Xi = 193 X2 = 173 $ = 31 Use this data to find the 99%...
