A study is to be made to estimate the proportion of residents of a certain city and its suburbs who favor the construction of a nuclear power plant near the city. How large a sample is needed if one wishes to be at least 90% confident that the estimate is within 0.06 of the true proportion of residents who favor the construction of the nuclear power plant?
A study is to be made to estimate the proportion of residents of a certain city and its suburbs who favor the construction of a nuclear power plant near the city. How large a sample is needed if one wishes to be at least 95% confident that the estimate is within 0.08 of the true proportion of residents who favor the construction of the nuclear power plant?
For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding. How hard is it to reach a businessperson by phone? Let p be the proportion of calls to businesspeople for which the caller reaches the person being called on the first try. LAUSE SALT (a) If you have no preliminary estimate for p, how many business phone calls should you include in a random sample to be 80% sure that the point estimate p will be within distance of 0.07 from p? (Round your answer up to the nearest whole number.) phone calls (b) A report states that businesspeople can be reached by a single phone call approximately 23% of the time. Using this (national) estimate for p, answer part (a). (Round your answer up to the nearest whole number.) phone calls
The duration (in minutes) for a sample of 20 flight-reservation telephone calls is shown in the following table: 2.1 10.4 4.8 5.5 4.5 2.8 5.9 10.5 4.8 3.3 5.8 6.6 7.5 4.8 5.5 3.5 5.3 3.6 7.8 6.0 NOTE: Ex=111 and x = 709.82 Assuming the population has a normal distribution, find a 95% confidence interval for the population mean time.
Suppose that for a test of proportion we have :p=0.5 and . The test statistic z=1.53 and the p-value is reported as P-value = 0.063. Find the error in the reasoning. This is a right-tailed test so the P-value should be 0.9370. This is a two-tailed test so the P-value should be 0.126. The P-value should have been calculated using the studentâ s t-distribution. There is no error in the reasoning. None of these.
Let p be the population proportion for the following condition. Find the point estimates for p and q. A study of 4677 adults from country A, 2619 think mainstream media is more interested in making money than in telling the truth. The point estimate for p, p, is (Round to three decimal places as needed.)
Epistasis is a phenomenon in which one gene controls the expression of another. In one case, a dihybrid cross should yield a 9:3:4 ratio. You collect the following data on mice: black coat: 138 brown coat: 46 white coat: 60 Is there any reason to doubt the ratio of 9 black : 3 brown : 4 white?

A study is to be made to estimate the proportion of residents of a certain city and its suburbs who favor the construction of a nuclear power plant near the city. How large a sample is needed if one wishes to be at least 90% confident that the estimate is within 0.03 of the true proportion of residents who favor the construction of the nuclear power plant?
Consider the following statement: "Many studies have proven that the hand (or a kiss on the forehead) will be correct 98% if the time when there is no fever, but will be wrong half the time when an individual actually has a fever." Based on this excerpt, determine the sensitivity and specificity of using a "hand on the forehead" method to determine the presence of a fever. Explain.
Suppose 420 randomly selected people are surveyed to determine whether or not they subscribe to cable TV. Of the 420 surveyed, 250 reported subscribing to cable TV. What is the sample proportion for failures, q′? Round the final answer to three decimal places.
