- P2 given the relevant sample results. Assume the results come Use the normal distribution to find a confidence interval for a difference in proportions p from random samples. A 95% confidence interval for pı - P2 given that Pı = 0.20 with nį = 60 and P2 = 0.40 with n2 = 120 Give the best estimate for p - p2, the margin of error, and the confidence interval. Round your answer for the best estimate to two decimal...
Suppose x has a mound-shaped distribution with σ= 3. (a) Find the minimal sample size required so that for a 95% confidence interval, the maximal margin of error is E=0.4. (b) Based on this sample size, can we assume that the x distribution is approximately normal? Explain.
Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p , the margin of error, and the confidence interval. Assume the results come from a random sample. A 95% confidence interval for the proportion of the population in Category A given that 18% of a sample of 450 are in Category A. Round your answer for the point estimate to two decimal places, and your...
19. Assume that pulse rates of men follow a bell-shaped (normal) distribution with a mean of 74 beats per minute and a standard deviation of 12 beats per minute. a. Based upon the Empirical Rule, give an interval that contains about 95% of all such pulse rates. this has to be solved using excel functions (new versions)
