confused on the question

Problem 4: Suppose we want to estimate the total weight of the juice that can he extracted from a shipment of apples. The total weight of the shipment was found to he l pounds. We 1331-02 a random sampling of 5 apples from the shipment and measure the weight of these apples and the weight of their extracted juice. Apple number 1 2 3 =1 5 Weight of the apple [pound] [L26 [L41 [LE +3.32 [L33 Weight of the apple's juice (pound) 13.18 [L25 [119 13.21 [L24 Assume that the number of apples in the shipment is large. 1. Estimate the total weight of the juice that can be extracted from this shipment using ratio estimation. Compute its standard error. 2. lConstruct the 95% condence interval for the total weight of the juice. 3. lConstruct the 95% condence interval for the average weight of the juice that can be ex tracted from one pound of apple from this shipment
