A food inspector finds that 6% of the packaged spinach tested at one organic food distributor ...

Question 1.

A teacher has a morning class with 24 students, and they had a mean score of 84% on the midterm exam. The afternoon class has 28 students, and they had a mean score of 86% on the same exam. Does it follow that the mean score for both classes combined is 85%? Explain.

Question 2.

A food inspector finds that 6% of the packaged spinach tested at one organic food distributor contain

bacteria and 10% of the packaged spinach at another organic food distributor contain

bacteria. Does it follow that between the two organic food distributors, a total of 8% of the packaged spinach tested contain E. coli bacteria? Why or why not?
