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.

Question

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. After a 24-hour smoking abstinence, 23 smokers were asked to estimate how much time had passed during a 30-second period. The average amount of perceived time that elapsed was 35.758 seconds with a standard deviation of 10.787 seconds. Is there evidence at the 0.05 level that nicotine withdrawal has a negative impact on time perception - that is, the mean perceived time elapsed is greater than the actual time period of 30 seconds?    

  •  HoHo: Select an answer ȳ μ p p̂  ? ≠ < = >         HaHa:Select an answer μ p̂ p ȳ  ? = > ≠ <  
  • αα =  
  • Test Statistic: t =   (Note: round the t-score to two decimal places)
  • probability = Select an answer 0.0089 0.0178 0.9911   
  • decision: Select an answer Reject H₀ Fail to reject H₀ 
  • At the 0.05 level, there Select an answer is is not  significant evidence to conclude the mean perceived time elapsed is Select an answer less than different than greater than  than  seconds.
