Extracted text: A point estimate is the value from a sample that best approximates the parameter of interest. For instance, suppose you wanted to know the likelihood of getting heads with a coin flip. You flip a coin 80 times and get 44 heads. The point estimate would be 44/80. a) Suppose you want to find the average weight of an adult emperor penguin. The weight of five penguins are 46, 52, 49, 50, and 54 pounds. What is the point estimate for the average weight? pounds b) Suppose you want to find the proportion of students that are left handed? You notice that your class has 32 students, 4 of who are left handed. What is the point estimate for the proportion of left-handed students?
