Suppose a student did a research project to examine whether the genre of music produces different typing speeds in words. Participants attended this study individually and were asked to type predetermined lines while listening to different songs, which fit into different musical genre. The results showed that in 90 seconds the mean number of words typed was 55 for the participants listening to Rock music, and 51 words typed for the participants listening to Blues. What was the variable of interest in this research project? The student decided to perform a t test to answer his research question. Given the estimated standard error of the t distribution is .76, calculate the observed t statistic If the t test was an independent-samples t test, and there were 38 participants (15 in one group and 23 in another group) in the study, what is the critical value for this t test? Assuming alpha=.05. Did the student find significant testing result based on the t test above? Yes/ No

Question

Suppose a student did a research project to examine whether the genre of music produces different typing speeds in words. Participants attended this study individually and were asked to type predetermined lines while listening to different songs, which fit into different musical genre. The results showed that in 90 seconds the mean number of words typed was 55 for the participants listening to Rock music, and 51 words typed for the participants listening to Blues.

What was the variable of interest in this research project?

The student decided to perform a t test to answer his research question. Given the estimated standard error of the t distribution is .76, calculate the observed t statistic

If the t test was an independent-samples t test, and there were 38 participants (15 in one group and 23 in another group) in the study, what is the critical value for this t test? Assuming alpha=.05.

Did the student find significant testing result based on the t test above? Yes/ No
