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:
Answer:
3b
Step-by-step explanation:
2x + 4 = b
3(2x+4) = 3b
6x + 12 = 3b
Algebraic expression means Letter Can stand for numbers. Ex: 2y+5 and Y=10
