A random sample of 100 chemistry students were asked how many lab classes he or she was enrolled in September 2000. The results showed a mean of 1.65 lab classes with a standard deviation of 1.39. Ten years later, a similar survey was conducted to determine if the distribution changed. The 2010 sample mean was 1.82 with a standard deviation of 1.51. Do the data provide statistical evidence that the mean number of lab classes taken in the first survey is different from the survey taken 10 years later? Perform the appropriate test using a = 0.02​
