Consider the population of four juvenile condors. Their weights in pounds are : 2, 4, 5, 10

(a) Let $x$ be the weight of a juvenile condor. Write the possible unique values for $x$: (NOTE: Separate each value in the list with a comma.) .

(b) Find the mean of the population:

(c) Let $\bar x$ be the average weight from a sample of two juvenile condors. List all possible outcomes for $\bar x$. (If a value occurs twice, make sure to list it twice.) This is the sampling distribution for samples of size 2: (NOTE: Separate each value in the list with a comma.) .

(d) Find the mean of the sampling distribution:
