2. In the study described in the paper, "Exposure to Diesel Exhaust Induces Changes in EEG in Human Volunteers," 10 healthy mean were exposed to diesel exhauust for 1 hour. A measure of brain activity (called median power frequency, or MPF in Hz) was recorded at the same location in the brain both before and after the diesel exhaust exposure. The resulting data are given in the accompanying table. For purposes of this exercise, assume that the sample of 10 men is representative of healthy adult males. 4. 74 8.7 9.8 10 Subject MPF Before (in HZ) 6.4 MPF After (in HZ) Difference 3 5. 8. 7.4 6.6 8.9 8.7 8.0 12.6 8.4 9.0 8.4 11.0 14.4 11.3 7.1 11.2 8.9 9.3 Construct and interpret a 90% confidence interval estimate for the difference in mean MPF before and after exposure to diesel exhaust.

Would love the answer to all but most important the calculate section when trying to find the confidence interval!

2. In the study described in the paper, "Exposure to Diesel Exhaust Induces Changes in EEG in Human Volunteers," 10 healthy mean were exposed to diesel exhaust for 1 bour. A measure of brain activity (called median power frequency, or MPF in Hz) was recorded at the same location in the brain both before and after the diesel exhanst exposure. The resulting data are given in the accompanying table. For purposes of this exercise, assume that the sample of 10 men is representative of healthy adult males.
