AP Stat Unit 3 Progress Check MCQ Part BA company famous for its nacho-flavored corn chips has developed two new formulas, A and B, which they hope their customers will like even more than the original formula. To determine whether customers prefer one of the new formulas over the current nacho flavoring, a sample of 50 customers is obtained. Each customer tastes both formula A and formula B in a randomly assigned order and indicates which one they prefer more. Which of the following best descri...

A trainer is studying the effects of vitamin D on his athletes. He has realized that there are many potential confounding factors, such as gender and age. To limit the effect of these confounding variables, he decided to first group two athletes together based on these variables (for example, two 21-year-old males). Then he randomly assigned one person to receive the vitamin D and the other to receive a sugar pill. What type of experimental design does this situation demonstrate? Complete...

BIO 182 Justify your response to the previous question. For the design that you selected, BIO 182 Justify your response to the previous question. For the design that you selected, explain why this design minimizes any bias caused by uncontrolled variables associated with the location of a treatment. For each design that you rejected, explain why this design does not minimize any bias caused by uncontrolled variables associated with the location of a treatment.Selected Design: Randomized Block ...

Two amateur gardeners are interested in comparing the yields of two varieties of tomatoes. They each have small backyard gardens. Each gardener is going to plant three plants of each variety in his garden. The first gardener will select six small areas in his garden for planting, then choose three of these at random for the three plants of the first variety and then use the remaining three for the second variety. The second gardener will follow the same procedure with his own randomization in hi...
