Thomas collected 29 responses to a survey and used a two-tailed test to establish a significance level of 0.20 and calculate a 90% confidence interval. Using the t-table (located in the tutorial), what is the critical t-value used for calculating a 90% confidence interval with 28 degrees of freedom?

6. A two-tailed hypothesis test for a repeated-measures research design Previous studies have shown that playing video games can increase visual perception abilities on tasks presented in the gaming zone of the screen (within 5 degrees of the center). A graduate student is interested in whether playing video games increases peripheral visual perception abilities or decreases attention to peripheral regions because of focus on the gaming zone. For his study, he selects a random sample of 81 adults. The subjects...

10. The t test for two independent samples - One-tailed example using tables Most engaged couples expect or at least hope that they will have high levels of marital satisfaction. However, because 54% of first marriages end in divorce, social scientists have begun investigating influences on marital satisfaction. [Data source: This data was obtained from the National Center for Health Statistics.] Suppose a clinical psychologist sets out to look at the role of sexual orientation in relationship longevity. He decides...

A graduate student in education has developed an mathematical intervention program for under-performing school children. To test the effectiveness of his intervention he administers a math skills assessment at the beginning of the school year to a sample of n-25 students. He then implements the program throughout the year and re-assess the students again at the end of the school year. On average there was a 3 point difference between time 1 and time 2, with a variance value of...
