In September 2000, each student in a random sample of 100 chemistry majors at a large university was asked in how many lab classes he or she was enrolled. The results indicated a mean of 1.65 lab classes and a standard deviation of 1.39. To determine whether the distribution changed over the past 10 years, a similar survey was conducted in September 2010 by selecting a random sample of 100 chemistry majors. The results indicated a sample mean of 1.82...
