In a random sample of six people, the mean driving distance to work was 18.8 miles and the standard deviation was 4.5 miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 90% confidence interval for the population mean µ. Interpret the results. Identify the margin of error. (Round to one decimal place as needed.) Construct a 90% confidence interval for the population mean. (Round to one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) A. % of all random samples of six people from the population will have a mean driving distance to work (in miles) that is between the interval's endpoints. % confidence, it can be said that most driving distances to work (in miles) in the population are between the interval's endpoints. % confidence, it can be said that the population mean driving distance…

From a sample with n=40, the mean duration of a geyser's eruptions is 3.13 minutes and the standard deviation is 0.82 minutes. Using Chebychev's Theorem, determine at least how many of the eruptions lasted between 1.49 and 4.77 minutes.
A light bulb manufacturer guarantees that the mean life of a certain type of light bulb is at least 754 hours. A random sample of 30 light bulbs has a mean life of 732 hours.

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 43 feet. Assume the population standard deviation is 4.6 feet. The mean braking distance for Make B is 46 feet. Assume the population standard deviation is 4.5 feet. At α=0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. The critical value(s) is/are Find the standardized test statistic z for μ1−μ2.
A population has parameters u = 189.5 and o = 61.9. You intend to draw a random sample of size n = 113. What is the mean of the distribution of sample means? What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.)

A nutritionist selected a random sample of n = 50 adult males. The average daily intake of dairy products was found to be x (bar above) = 756 grams per day, with a standard deviation of s = 35 grams per day. Use this sample information to construct a 95% confidence interval for the mean daily intake of dairy products for men.
Suppose a randomly selected sample of n = 69 men has a mean foot length of x = 28.3 cm, and the standard deviation of the sample is 3 cm. Calculate an approximate 95% confidence interval for the mean foot length of men. (Round the answers to one decimal place.) to cm

A manufacturer claims that the mean lifetime, u, of its light bulbs is 54 months. The standard deviation of these lifetimes is 6 months. Nineteen bulbs are selected at random, and their mean lifetime is found to be 50 months. Assume that the population is normally distributed. Can we conclude, at the 0.05 level of significance, that the mean lifetime of light bulbs made by this manufacturer differs from 54 months? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)
