We need at least 601 incomes.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
How many such incomes must be found if we want to be 95% confident that the sample mean is within $500 of the true population mean?
We have to find n, for which . So
Rounding up
We need at least 601 incomes.

so... if Julia folded the paper, in a way that P was on top of Q, that means the crease is running through the half-way point or midpoint, that means that, if the segment PQ is 2.4, the segments on either side of the crease, PS and QS are both two equal halves.
