Question

A sample of stalactites (a type of rock formation) found in a glow worm cave
produced the following lengths in cm:
9.6
16.9 15.1 14.3 15.9 17.2 13.0
17.1
15.4 16.2 4.5
20.3 21.2 15.7
Assuming that this sample came from a normal population, calculate a 95%
confidence interval for the mean length of stalactites in the cave.

A study of the longleaf pine trees in Wade Tract in Thomas County, Georgia measures the diameter at breast height (DBH) for each tree. This is the diameter of the tree at 4.5 feet and the units are in centimeters (cm). Only trees with DBH greater than 1.5 cm were sampled. A random sample of 40 trees had mean 27.9 cm and a standard deviation of 17.7 cm. We are interested in whether the mean DBH of the longleaf pine tree is greater than 25 cm. Test this claim. a. State the hypotheses for this problem. b. Calculate the value of the test statistic. c. Calculate and interpret the p-value. d. State your conclusion in terms of the problem.
A company has developed an electric car they say can travel over 500 mues on a single charge. A consumer car magazine wants to test this claim. The magazine randomly selects 16 owners of the car and ask them to measure how far the car can travel on a full charge. The mean distance traveled by these 16 cars was 510 miles with a standard deviation of 20 miles. Test the hypothesis that the mean distance the car can travel on a single charge is greater than 500 miles. Use a 0.05 level of significance. (Assume that the distances the car can travel on one charge are normally distributed.) (a) State the null and alternative hypothesis. (b) Will this be a right-tailed, left-tailed, or two-tailed test? (c) Calculate the test statistic assuming the null hypothesis is true. T = %3D (d) Use the test statistic to calculate the P-value for the test. P- value = (e) Does the data provide enough evidence to conclude that, at the 5% significance level, the mean distance this car can travel with a full…

A manufacturer of college textbooks is interested in the strength of the bindings produced by a particular binding machine. Strength can be measured by recording the force required to pull the pages from the binding. If this force is measured in pounds, how many books should be tested to estimate the average force required to break the binding within .5 pounds with 90% confidence. Assume the population standard deviation is 0.4 pounds. 2.

Acrylic bone cement is sometimes used in hip and knee replacements to fix an artificial joint in place. The force required to break an acrylic bone cement bond was measured for eight specimens under specified conditions, and the resulting mean and standard deviation were 306.17 newtons and 41.96 newtons, respectively. Assuming that it is reasonable to believe that breaking force under these conditions has a distribution that is approximately normal, estimate the mean breaking force for acrylic bone cement under the specified conditions using a 95% confidence interval. (Round your answers to three decimal places.)
