To determine how the randomizations is done in the experiment.
The randomization is done by assigning the cloths to two different groups at random.
The cloths are numbered from 1 to 20 and using graphing calculator command, 10 random numbers are generated to select cloths for one of the groups. Remaining are placed in the another group.
Given information:
A company wants to test the effectiveness of a new additive for the detergent.
20 identical cloths with dirt and stains are considered.
Explanation:
An Experiment is a study of cause-and-effect between the variables.
20 cloths should be considered in two groups.
Randomization:
Students are assigned to different groups randomly.
Randomization is done in following steps:
Step 1: The volunteers are numbered form 1 to 20.
Step 2: Using the graphing calculator command
Step 3: 10 distinct numbers are generated and are considered in group 1
Step 4: Remaining 10 are placed in group 2
Generate random numbers using calculator:
- Go to Math
- Go to Prb
- Select 5

- 3. True False. If false create functions that prove it is false. Note: f(x) = g(x). a) If_lim ƒ(x) = ∞ and_lim g(x) = ∞,then_lim [ƒ(x) − g(x)] = 0 x→ 0+ x→0+ x→0+ b) If h(x) and g(x) are continuous at x = c, and if h(c) > 0 and g(c) = 0, then h(x) lim. will = x→c g(x) c) If lim f(x) = 0 and lim g(x) = 0 then lim f(x) does not exist. x-a x-a x→a g(x)arrow_forwardPls help ASAParrow_forward15. a) Consider f(x) = x-1 3x+2 and use the difference quotient to determine the simplified expression in terms of x, for the slope of any tangent to y = f(x). Also, determine the slope at x = 2. 15 b) Determine the equation of the tangent to f(x) at x = 2. Final answer in Standard Form Ax + By + C = 0, A ≥ 0, with no fractions or decimals.arrow_forward
