The MBA program coordinator has been commissioned by the Faculty Board to analyze the starting monthly salaries for freshly employed Bcom graduates. The coordinator selected a random sample of starting monthly salaries of recently freshly employed Bcom graduates and obtained the following data: Salary (Ksh 000) 15-24 25-34 35-44 45-54 55-64 65-74 75-84 No. of graduates 5 10 15 30 20 15 5 Suppose salaries for freshly employed graduates are classified as “poor” and “good” when they fall below Kshs.42, 000 and above Kshs.62, 000 respectively, otherwise as “normal”. What proportion of freshly employed graduates would be expected to fall in each salary category?

Use the following choices to find examples of the three types of heredity-environment correlations that we learned about in class. Assume that the specific characteristics of the individuals described all have a demonstrated connection to heredity (i.e., research has shown that one's genes are a relevant factor). Lisa has a quick temper, just like her father. Whenever she gets irritated, she acts first and thinks later, which sometimes gets her into trouble, depending on the situation. She even says the same swear words she has heard him use around the house as she grew up. Yesterday, she swore in front of a 2-year-old, and promptly was lectured by her friend.
