Due Fri 11/18/2022 11:59 pm Show Intro/ Instructions Questions A study conducted by researchers at Pennsylvania State University investigated whether time perception, an indication of a person's ability to concentrate, is impaired during nicotine withdrawal.

The average amount of perceived time that elapsed C Q1 (1/3) was 35.013 seconds with a standard deviation of 10.937 seconds. Is there evidence at the 0.05 level that nicotine withdrawal has a negative impact on time perception - that is, the mean Q 2 [5/5] perceived time elapsed is greater than the actual time period of 30 seconds?
