In a study examining the effect of room temperature on academic performance, researchers tested knowledge of basic statistical concepts for two groups of Introduction to Statistics students who took their exams in rooms with different temperatures. One group took their exam in a room heated to 70 degree Fahrenheit and the second group in a room heated to 90 degrees Fahrenheit. The mean number of items student correctly answers in the 70 degree room (M=7.9 out of 10) was significantly...

4. Refrigeration and air conditioning is quite useful, but it is, in effect, a way to move heat from a low temperature to a high temperature. Is this possible, given the second law? Answer the following questions below, for R-134a (a common refrigerant), and then state whether you believe refrigeration violates the second law, and why (or why not) a. R-134a arrives to the inside of the refrigerator that you are trying to keep cooled to T- 4°C. The air...

(2) In an experiment designed to study effects of illumination level on task performance2, subjects were required to insert a fine-tipped probe into the eyeholes of ten needles in rapid succession both for a low light level with a black background and a higher level with a white background. Each observation is the time each subject took for task completion. (a) Estimate the true mean difference in completion time with 95% confidence. Interpret (b) Does the data indicate that the...
