A Cognitive Psychologist Tested Whether People Spend More Time Looking $\pm$

A cognitive psychologist tested whether people spend more time looking at and comprehending content words (e.g. ,ball,kick) than other words (the,a) when reading a passage.The mean looking time for a sample of content words was compared to the mean looking time for the population of other words by transforming it into a z-score.The z-score for the sample mean was z = 3.00.With critical values of $\pm$ 1.96,what should the psychologist conclude about the sample mean?

A) It is an unlikely sample for the population of looking times for other words and probably represents some other population (looking times for meaningful words) .
B) Because of chance,the sample simply represents the population of looking times for other words poorly.
C) Because of chance,the sample probably represents some other population (looking times for meaningful words) .
D) It is an unlikely sample for the population of looking times for other words,but it simply represents the population poorly.
