Using the formula ,compute a 95% confidence interval for a population proportion given the sample proportion is 0.24 and the sample size is 1014. Round your answers to 4 decimal places, e.g. 0.7523. 0.0263
sample proportion = 0.24 and sample size n = 1014
z critical for 95% is 1.96
Using the formula ,compute a 95% confidence interval for a population proportion given the sample proportion...
a. You wish to compute the 95% confidence interval for the population proportion. How large a sample should you draw to ensure that the sample proportion does not deviate from the population proportion by more than 0.12? No prior estimate for the population proportion is available. Round intermediate calculations to at least 4 decimal places and "z" value to 3 decimal places. Round up your answer to the nearest whole number.) Sample Size - b. A business student is interested...
Compute the 95% confidence interval estimate for the population proportion, p, based on a sample size of 100 when the sample proportion, is equal to 0.28. What is the upper bound of this confidence interval? (Round to three decimal places as needed.)
Using the sample of size 200, construct a 95% confidence interval for the proportion of Youth Survey participants who would describe themselves as being about the right weight (Round to three decimal places.) Sample Proportion = Margin of error Lower limit Upper limit Does your 95% confidence interval based on the sample of size 200 include the true proportion of Youth Survey participants who would describe themselves as being about the right weight? O Yes O No
Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of .n=7. 1, 2, 3, 4, 5, 6, and 15 <-----this is the data In the given data, replace the value 15 with 7 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 95% confidence interval for the population mean,...
Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 155 with 20 successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 95% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
Construct a 95% confidence interval of the population proportion using the given information. x = 120, n = 200 The lower bound is The upper bound is (Round to three decimal places as needed.)
Construct a 95% confidence interval of the population proportion using the given information. x = 175, n = 250 The lower bound is The upper bound is . (Round to three decimal places as needed.)
Construct a 96% confidence interval to estimate the population proportion with a sample proportion equal to 0.36 and a sample size equal to 100. Click the icon to view a portion of the Cumulative Probabilities for the Standard Normal Distribution table A 95% confidence interval estimates that the population proportion is between a lower limit of (Round to three decimal places as needed) and an upper limit of
Assume that a sample is used to estimate a population proportion p. Find the 95% confidence interval for a sample of size 186 with 56% successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. Confidence interval = Express the same answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places. < p < Express the same answer using the point estimate and margin of error. Give your...
Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n=8.1, 2, 3, 4, 5, 6, 7, and 24 In the given data, replace the value 24 with 8 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general.Find a 95% confidence interval for the population mean, using the formula or technology.Round answer to two decimal places
