For a given N, the interval that bounds the population mean at the 99% confidence level is greater than that which bounds the population mean at the 95% confidence level.
Increases confidence level then margin of error also increases therefore, 99% confidence interval > 95 % confidence interval.

In constructing and a 99% confidence interval of the population proportion at the given level of confidence. x = 195, n = 300, what is the margin of error.
The 99% confidence interval of a population mean is (1,7). One of the following is the 95% confidence interval. Which is it? (a) (2,6) (b) (1,6) (c) (0,8) (d) (2,7)
Construct a 99% confidence interval to estimate the population mean using the data below. X = 46 o = 12 n42 With 99% confidence, when n = 42 the population mean is between a lower limit of (Round to two decimal places as needed.) and an upper limit of Construct a 95% confidence interval to estimate the population mean with X = 102 and o = 25 for the following sample sizes. a) n = 32 b) n = 45...
Construct a 99% confidence interval to estimate the population mean using the following data. What assumptions need to be made to construct this interval? x=88 20 n 11 What assumptions need to be made to construct this interval? Tre O A. The population mean will be in the confidence interval. en OB. The sample size is less than 30. et c . The population must be normally distributed. D. The population is skewed to one side. With 99% confidence, when...
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,...
Construct a 99% confidence interval to estimate the population mean using the following data. What assumptions need to be made to construct this interval? x overbar = 95 σ = 21 n = 10 With 99% confidence, when n = 10 the population mean is between the lower limit of _____ and the upper limit of ____. What is the formula with a step by step guide on how to solve this equation?
Match the confidence level with the confidence interval for the population mean. 1. ?bar±2.575(?/√n) 2. ?bar±1.645(?/√n) 3. ?bar±1.282(?/√n) A. 80% B. 90% C. 99%
Construct a confidence interval of the population proportion at the given level of confidence. x- 120, n 1200, 99% confidence The lower bound of the confidence interval is (Round to three decimal places as needed.) The upper bound of the confidence interval is (Round to three decimal places as needed.) Construct a 99% confidence interval of the population proportion using the given information. X 105, n 150 The lower bound is The upper bound is (Round to three decimal places...
Use the given level of confidence and statistics to construct a confidence interval for the population mean µ. Assume that the population has a normal distribution. A laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with s= 17.6 milligrams. Construct a 95% confidence interval for the true mean
Assuming that the population is normally distributed, construct a 99% confidence interval for the population mean, based on e ollowing sample sizeof 1, 2, 3, 4, 5, 6, 7, and 25 In the given data, replace the value 25 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 99% confidence interval for the population mean, using the formula or technology....
