Questions 6 – 7 refer to the following scenario: The number of eggs in robin nests varies from nest to nest (of course). If X is the number of eggs in a randomly selected robin nest, then X has the following probability distribution:  

Two researchers (A and B) are testing the following hypotheses:

Suppose we select 100 navel oranges independently and randomly. What is the approximate probability that at least 61 of them have at least 13 grams of sugar?   Use only the approximation method we studied in class to answer this question.

What proportion of navel oranges have more than 10 grams of sugar?

Questions 4 – 5 refer to the following scenario: Students in a class take an exam. The amount of time that a randomly selected student in this class takes to finish the exam is given by random variable X, which has the following probability density function:

Based on the same sample, a 90% confidence interval would be 

What proportion of robin nests have more than 5 eggs?
