1) $19950/$15= 1330 tickets
2) 1330*$20=26600
This year, the school made $26600

You can do this 2 ways. First, you can determine the new cost compared to last year as 20/15 or 4/3. So multiply 4/3×$19950=$26,600
Second, you can look at it as 19950÷15 to find how many tickets sold last year and then multiply by $20, the new price

Answer:

The answer is "0.3206".

Step-by-step explanation:

H_0: p_1 = p_2\\\\H_a: p_1 \neq  p_2\\\\\hat{p_1} = \frac{X_1}{N_1} = \frac{53}{400} = 0.1325\\\\\hat{p_1}= \frac{X_2}{N_2} = \frac{78}{500}= 0.156\\\\\hat{p} = \frac{(X_1 + X_2)}{(N_1 + N_2)} = \frac{(53+78)}{(400+500)} = 0.1456

Testing statistic:

z = \frac{(\hat{p_1}- \hat{p_2})}{\sqrt{(\hat{p} \times (1-\hat{p}) \times (\frac{1}{N_1} + \frac{1}{N_2}))}}

=\frac{(0.1325-0.156)}{\sqrt{(0.1456\times (1-0.1456)\times (\frac{1}{400} + \frac{1}{500}))}}\\\\ = -0.99

Calculating the P-value Approach

\text{P-value}= 0.3206

\pi 5^2*10 \pi
apply exponent rule
=5^2*10 \pi ^2
=10*25 \pi ^2
multiply the numbers:25x10=250
=250 \pi ^2
refine to a decimal form
=2467.40110
Hope this helps :)
