Chapter 11: Using the attached dataset “Chapter 11 Data Set 1” to test the research hypothesis that males raise their hands in class more often than females. (Please note that these data are not exactly the data provided by the author). Is this a directional or non-directional hypothesis? Should you use a one-tailed or two-tailed test? What is the corresponding null hypothesis? Conduct the between groups t-test using Excel (either method). Use the .05 confidence level. What is your conclusion about the null hypothesis?

Using the methods in Section 11.1, test the hypothesis (α = 0.05) that the population proportions of red and brown are equal (pred = pbrown). You are testing if their proportions are equal to one another. NOTE: These are NOT independent samples, but we will use this approach anyway to practice the method. This also means that n1 and n2 will both be the total number of candies in all the bags. The “x” values for red and brown are...

In a research project, researchers collected demographic and health data from a sample of elderly residents in the community. To examine any possible gender differences in their sample, they want to see if the females and the males differ significantly on the education level (number of years of formal schooling). The researchers are not predicting any direction in the possible gender differences so the hypotheses should be non-directional. They would like to run a two-tailed test with α = .10....
