Week Four Practice Problems Prepare a written response to the following questions. Chapter 7 The table below shows ratings of various aspects of work and home life of 100 middle-class men in India who were fathers.

The chart is broken down into three different ranges showing comparisons for Work vs Home. This chart show the men have a high value of the importance of work with a t score of 6.86 They also show a high interest in challenges in the work place with a score of 11.49 As far as their Choice to change they seem to be pretty content with a Wish doing else @.61 Chapter 8 Barker and colleagues (2012) compared 61 parents fo children who had a serious mental illness (SMI) to 321 parents of children withour such an illness. The researchers examined the parents reported levels of stress, their levels of a hormone called cortisol (levels of this hormone provide an indication of chronic stress), and their use of several types of medication. The table below shows the results of the study. Focusing on the parents number of stressors (the first row of the table) and the parents use of medications for anxiety or depression (the last row in the table), explain these results to a person who knows about the t test for a single sample but is unfamiliar with the t test for independent means.

For each of the following studies, say whether you would use a t test for dependent means or a t test for independent means. A researcher measures the heights of 40 university students who are the firstborn in their families and compares the 15 who come from large families to the 25 who come from smaller families. A researcher tests performance on a math skills test of each of 250 individuals before and after they complete a one-day seminar on managing test anxiety. A researcher compares the resting heart rate of 15 individuals who have been taking a particular drug to the resting heart rate of 48 other individuals who have not been taking the drug. Chapter 9 An experiment is conducted in which 60 participants each fill out a personality test, but not according to the way the participants see themselves. Instead, 15 are randomly assigned to fill it out according to the way they think theur mothers see them (that is, the way they think their mothers would fill it out to describe the participants) 15 as their fathers would fill it out for them 15 as their best friends would fill it out for them 15 as the professors they know best would fill it out for them. The main results appear in Table 9-17. Explain these results to a person who has never had a course in statistics.

Students were randomly assigned to three different experimental conditions involving different methods of writing a summary. At the end of the two days of instructions, participants wrote a summary. One of the ways it was scored was the percentage of specific details of information it included from the original material.
