A sample size must be determined for estimating a population mean given that the confidence level is 99​% and the desired margin of error is 0.24. The largest value in the population18 is thought to be and the smallest value is thought to be 6 .

For a confidence level of 94%, find the critical value for a confidence interval on a one sample proportion.

A statistics practitioner took a random sample of 59 observations from a population whose standard deviation is 32 and computed the sample mean to be 95. Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits. A. Estimate the population mean with 95% confidence. Confidence Interval = B. Estimate the population mean with 90% confidence. Confidence Interval= C. Estimate the population mean with 99% confidence. Confidence Interval=

A confidence interval for a population mean has a margin of error of 0.047. a. Determine the length of the confidence interval.b. If the sample mean is 0.205, obtain the confidence interval.c. Construct a graph that illustrates your results.

A statistics practitioner took a random sample of 43 observations from a population whose standard deviation is 30 and computed the sample mean to be 109.   Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits.   A. Estimate the population mean with 95% confidence.   Confidence Interval =  B. Estimate the population mean with 90% confidence.   Confidence Interval =  C. Estimate the population mean with 99% confidence.   Confidence Interval =

A confidence interval for a population proportion p is 0.635 to 0.700. What is the margin of error?

Assume that population means are to be estimated from the samples described. Use the sample results to approximate the margin of error and​ 95% confidence interval.   Sample size=64​, sample mean=69​, sample standard deviation=7 what is the margin of error

Tina catches a 14-pound bass.  She does not know the population mean or standard deviation.  So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds.  Find the t and calculate a 95% (α = .05) confidence interval.

Given the following: Sample Mean = 84.3 Population Variance = 144 Sample size = 35 a. Calculate a 90% confidence interval for the mean. Interpret this interval. b. Calculate a 99% confidence interval for the mean. c. Explain the relationship between Confidence Levels and the resulting intervals.
