Now we have to change all of the numerators to match the denominators. Since 5 goes into 20 four times.. 2 x 4 = 8 8/20
Since 4 goes into 20 five times... 3 x 5 = 15 15/20
Since 2 goes into 20 ten times... 1 x 10 = 10 10/20
Our new fractions are.. 8/20+15/20+10/20=?
Now just add the numerators. 33/20
If you want to simplify it to a mixed number, your answer is 1 13/20 If you want to keep it as a fraction, it's already in simplest form. So the answer is 33/20
(B) Yes, because sampling distributions of population proportions are modeled with a normal model.
Step-by-step explanation:
Here we have the condition for normality being that where we have a population with a given mean and standard deviation, while a sufficiently large sample is drawn from the population while being replaced, the distribution of the sample mean p will be distributed normally according to central limit theorem.
