49. A The 95% confidence interval for the population mean is. In this particular problem, we have. Using df = n – 1 = 4, we look up (in a table) that t.025 = 2.776. Then our confidence interval is. 50. C Assumptions for the confidence interval for the mean are as follows: data is quantitative, random sample, data comes from a normal distribution.

A random sample of 100 movie theaters showed that the mean price of a movie was $7.00 with a standard deviation of $.80. Construct a 99% confidence interval for the population mean . Find n: A researcher wants to determine the 99% confidence interval for the mean number if hours per week that adults spend doing community service.

Compute a 95% confidence interval for a sample of 50 items, where the mean was computed to be 20, and the population standard deviation is known to by 10. Solution: Note that since the population standard deviation is known we can use the “z” interval. Step1: make sure you are on the “confidence interval” worksheet (there are 3 worksheets)

In particular, consider the notion of estimating the unknown mean μ for a population based on the data obtained from a random sample drawn from that population. The confidence interval so constructed is centered at the sample mean and extends sufficiently far in each direction so as to have a pre-determined probability of containing μ.

8.1 - Confidence Intervals: The Basics (pp. 475-492) Activity. Suppose we have a Normally distributed population with mean = M and standard deviation = 20. As we saw in Chapter 7, if we take repeated random samples from the population, compute the sample means and average them, we have an unbiased estimator of the population mean.

(8.3) Confidence Interval for a Mean Practice. The purpose of a confidence interval is to estimate an unknown population parameter using a sample statistic, with an indication of how accurate the estimate is (+/–) and of how confident we are that the result is correct (95%).

We will use confidence interval estimates based on sample data to estimate a population average (mean) and to estimate a population proportion. Confidence intervals for means and proportions are symmetric; the point estimate is at the center of the interval. The endpoints of the interval are found as.

Apr 29, 2013 · Determine and interpret a 90% confidence interval for the mean BAC in fatal crashes in which the driver had a positive BAC. The 90% confidence interval for the mean BAC is (0.147, 0.153). Round to the nearest thousandth. We are 90% confident that the mean BAC in fatal crashes in which the driver had a positive BAC is in the interval (0.147, 0.153).
