9 (C) (a) You give your students the following problem: "You just bought 30 beads of which 18are gold and identical and 12 are silver and identical. You want to line them up in arow. How many different arrangements of the beads can you make?" Elizabethsolves the problem by finding the number of distinguishable permutations of 30objects, 18 alike of one kind and 12 alike of another kind. That is, she uses theresult of the previous problem. Natalie solves the problem by finding the number ofcombinations of 30 different objects taken 18 at a time. Who is correct?(b) Does the number of permutations of n objects, ralike of one kind and n r alike of anotherkind, always equal the combinations of n different objects taken r at a time? Explain.

For a cooking oil company, the price they are paid for coconuts in large shipments is based on the amount of coconut extract from the load. Therefore, there is a need to determine the amount of coconut extract in the whole load prior to extraction. A sample of n coconut can be taken and find y1, . . . , yn , the amount of coconut extract in these coconuts. Ny is hard to get in this case because N is hard to count. How can the total amount of coconut extract from a load shipment be measured? Using the total weight would be a good idea and easy to obtain. The relationship between the weight of the load and the weight of the coconut extract one obtains can be used. As it turns out, 15 coconuts selected by simple random sampling were weighed and also extracted. The total weight of the coconut shipment was found to be 900 kg. Given these results (below): look at the table (pic) Question: For this data, which is the more accurate estimate, the ratio estimator or the ordinary SRS…
