Lotioneer introduced a new formula for their skin lotion. They want to conduct an experiment to compare skin dryness of people using the new formula with those using the current formula
Information on the eight volunteers is shown in the table
Volunteer Gender Age, year
1 Male 23
2 Female 25
3 Female 51
4 Female 24
5 Male 22
6 Male 53
7 Male 52
8 Female 56
Part A: The scientists running the experiment think skin dryness is based on age, not gender. Create four blocks of two volunteers and identify the volunteers, by number, who would be
Included in each block. Explain the criteria you used to create the blocks. (3 points)
Part B: The company brings in an outside analysis firm that believes skin dryness changes based on age and gender. The firm also uses block design with four blocks of two volunteers for each
block. Group the volunteers, by number, who would be included in each block. Explain the criteria you used to create the blocks (3 points)
Part C: The outside analysis firm from the part B assigns treatments by giving treatment by giving two block the new formula and two blocks the current formula. Did they assign the treatment appropriately? If so, explain a suitable process for selecting the blocks that receive the new formula. If not, explain a suitable method for assigning treatments
