A dairy farmer thinks that the average weight gain of his cows depends on two factors: the type of grain that they are fed and the type of grass that they are fed. The dairy farmer has four different types of grain from which to choose and three different types of grass from which to choose. He would like to determine if there is a particular combination of grain and grass that would lead to the greatest weight gain on average for his cows. He randomly selects three one-year-old cows and assigns them to each of the possible combinations of grain and grass. After one year he records the weight gain for each cow (in pounds) with the following results. Is there sufficient evidence to conclude that there is a significant difference in the average weight gains among the cows for the different types of grain?

Researchers conducted a study to find out if there is a difference in the use of online-learning by different age groups. Randomly selected participants were divided into two age groups. In the 16 to 29-year-old group, 7% of the 628 surveyed use online-learning, while 11% of the 2,309 participants 30 years old and older use online learning. (Set 1 for 16-29 year old group; Set 2 for 30 years old and older). Find X2.

Four third graders participate, 2 boys and 2 girls. For each child, a marble is drawn without replacement from a bucket containing 2 red marbles and 2 blue marbles. If a red marble is selected, the child gets a pen and if blue, the child gets a pencil. The children are assigned in this order: boy 1, girl 1, boy 2, girl 2. LetX be the number of boys assigned to a pen. Find E (X). Find SD(X). а. b.arrow_forwardvideo gamer believes that team composition greatly affects win rate. To test this idea, the player decides to play 100 matches with teams of 3 colors: Red, Green, and Blue. The player records the number of matches he wins with each team color. Given anecdotal evidence, the gamer believes his red team is the best and therefore will win the most games. He has less experience with his blue and green team and is interested to see if there is a difference between the two. Because the gamer is more experienced with his red team, he plays more matches with that team. The total number of matches played per team color is: Red-50, Blue-23, and Green 27. a) What is the IV of this experiment? What are the levels of the IV?
