Let population of 4 juvenile condors. The weights in pounds are : 3, 4, 6, 9
(i) Let x be weight of the juvenile condor. Write possible unique values for x: Separate each value in list with comma.
(ii) Determine mean of population.
(iii) Let \bar x be average weight from the sample of two juvenile condors. Write all possible outcomes for \bar x. (If value occurs twice, ensure to list it twice.) This is sampling distribution for samples of size 2.
(iv) Determine mean of sampling distribution.
