Answer:
Those steps shows the result of applying the subtraction property of equality, In which an integer value is subtracted from both the sides. Step 3 show the subtraction property of equality.
Step-by-step explanation:
The given expression is
Step 1: Use Distributive property
Step 2: Add like terms.
Step 3: Subtract 6 from both sides
(Subtraction property of equality)
Step 4: Divide both sides by 3.
Therefore those steps shows the result of applying the subtraction property of equality, In which an integer value is subtracted from both the sides.
So #2 is 2 students and #3 is 3/6

Answer:
Step-by-step explanation:
For this case we have the following data:
represent the random sample 1 selected
represent the proportion of success for the sample 1 selected
represent the random sample 2 selected
represent the proportion of success for the sample 2 selected
We know for this case that we can use the normal approximation since for both cases we have:
We have the randomization condition and we assume that the two samples are <10% of the entire population size.
So then we can use the following distribution for the proportions:
For this case we want to find the distribution for the difference of these two proportions and we have this:
So then the dtandard deviation would be given by:
