Hi Solve plz. 1. Find the number of possible ways to choose 2 apples, 1 orange, 1 papaya and 2 mangoes from a basket that contains 3 apples, 2 oranges, 2 papayas and 4 mangoes.

A farmer wishes to determine which of two brands of baby pig pellets, Kent or Moormans, produces better weight gains. Two of his sows each give birth to litters of 10 pigs on the same day, so he decides to give the baby pigs in litter A only Kent pellets, while the pigs in litter B will get only Moormans pellets. After 4 weeks , the average weigh tgain for pigs in litter A is greater than the average weight gain  for pigs in litter B. The feed they get is not the only factor affecting the rate at which pigs gain weight. Genetic differences also affect weight gain. It is likely that the pigs in litter A are genetically different from the pigs in litter B since the two litters have different mothers. What experimental design technique could the farmer use to take into account the genetic differences? A)placebo B) probability sampling C)Blocking D)observational study E)double-blinding

MAKE SURE YOU SELECT 2 ANSWERS FOR THIS QUESTION - Type of test and hypothesis. Professor Ratzo wonders if rats will run a maze faster for some kinds of foods than for others. He randomly assigns 30 rats to one of three conditions, 10 rats to each condition. Group 1 gets buttered bread at the end of the maze, Group 2 gets cheddar cheese, and Group 3 gets honey- glazed ham. The number of seconds each rat took to run the maze is recorded. The hypothesis is that type of food makes a difference in rat running time. Choose the type of test you should use to test this hypothesis? Then choose the correct hypotheses in symbol notation (or words if symbol is not appropriate).

Suppose that Karen, Sue, and Peter all work 6 hours a day. In an hour, Karen can make one widget or 2 thingamajigs. In an hour, Sue can make one widget or one thingamajig. In an hour, Peter can make 2 widgets or one thingamajig. If they all split their time evenly between making widgets and thingamajigs, how many thingamajigs can they make?

How do you solve this?
