A physiology student at NIU in 2002 believed that caffeine would cause a potassium measurement from urine to have a population mean different from 0. Measurements were taken from urine samples of 5 students. Assume that the measurements are a random sample from a normal distribution, that the sample mean of the measurements was .0906 and that the sample standard deviations of the measurements was .0806. Test the claim that the population mean of the measurements is different from 0. Use α =.05

A random sample of 16 students selected from the student body of a large university had an average age of 25 years and a standard deviation of 2 years. We want to determine if the average age of all the students at the university is less than equal to or greater than 24. Assume the distribution of the population of ages is normal. Using α = .05, it can be concluded that the population mean age is not different than...

1. An intelligence quotient, or IQ, is a measurement of intelligence derived from a standardized test such as the Stanford Binet IQ test. Scores on the test are normal distribution with a mean score of 100 and a standard deviation of 15. Draw 1000 samples of size n=9 from the distribution of IQ. Calculate the sample mean of all 1000 samples. Draw the histogram for all sample means in. What is the shape of the sample means? Calculate mean of...

8. Hypothesis testing with ANOVA Opinions about whether caffeine enhances test performance differ. You design a study to test the impact of drinks with different caffeine contents on students’ test-taking abilities. You choose 21 students at random from your introductory psychology course to participate in your study. You randomly assign each student to one of three drinks, each with a different caffeine concentration, such that there are seven students assigned to each drink. You then give each of them a...

A random sample of 49 measurements from one population had a sample mean of 16, with sample standard deviation 3. An independent random sample of 64 measurements from a second population had a sample mean of 18, with sample standard deviation 4. Test the claim that the population means are different. Use level of significance 0.01. (a) What distribution does the sample test statistic follow? Explain. The Student's t. We assume that both population distributions are approximately normal with known...

For a school, the principal expected that a student takes 45 minutes to travel to school on average. Suppose the time taken to travel to school by a student follows a normal distribution. 100 students are randomly selected from the school for interview and they took on average 44 minutes to travel to school with a standard deviation of 15 minutes. 6 of the selected students had lateness record in the last month. Construct a 95% confidence interval for the...
