Answer: The first set of expenses is 69.47% of second set of expenses.

Step-by-step explanation:

Since we have given that

Amount spend by Maria on lottery tickets every week = $21

Amount spend by Maria on food every month = $131

so, Amount spend by Maria on lottery in a year would be

21\times 52=\$1092

Amount spend by Maria on food in a year would be

131\times 12=\$1572

So, the first set of expenses is what % of the second set of expenses.

So, the required percentage would be

\dfrac{1092}{1572}\times 100\\\\=69.47\%

Hence, the first set of expenses is 69.47% of second set of expenses.

Explain how to perform a​ two-sample z-test for the difference between two population proportions.
Sati [7]
Point estimate for the difference between two population proportions is the difference between the two sample proportions, written as:

\hat{p}_1-\hat{p}_2

and the standard deviation is given by

\sqrt{\frac{\hat{p}_1(1-\hat{p}_1)}{n_1}+\frac{\hat{p}_2(1-\hat{p}_2)}{n_2}}

When np and n(1-p) is greater than 5, then the sampling distribution is approximately normal and we can use standard normal methods.

Thus, the propability of a test <span>for the difference between two population proportions is given by

P(X\ \textless \ x)=P\left(z\ \textless \  \frac{\hat{p}_1-\hat{p}_2}{\sqrt{\frac{\hat{p}_1(1-\hat{p}_1)}{n_1}+\frac{\hat{p}_2(1-\hat{p}_2)}{n_2}}} \right)</span>
