Answer:

We also know that we select a sample size of n =100 and on this case since the sample size is higher than 30 we can apply the central limit theorem and the distribution for the sample mean would be given by:

And the standard deviation for the sampling distribution would be:

So then the answer is TRUE
Step-by-step explanation:
Let X the random variable of interest and we know that the true mean and deviation for this case are given by:

We also know that we select a sample size of n =100 and on this case since the sample size is higher than 30 we can apply the central limit theorem and the distribution for the sample mean would be given by:

And the standard deviation for the sampling distribution would be:

So then the answer is TRUE
Remark
You have to read this carefully to know what way to write it.
One way you could write it would be
20 * x = 18 where x is the fraction. Now all you need do is divide.
Divide both sides by 20
20/20 * x = 18/20

But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.
18: 2 * 3 * 3
20: 2 * 2 *5
Cancel out the Highest common factor or 2.
You are left with
<<<< Answer
Jeese since she only ask 6th graders which is the subject of the survey and she ask at random so she doesnt show any bias
10+3=13
70/13=5.384615385
5.384615385*3= 16.15384615
So you would use 16 ounces of flour to 2 sig figs
