Answer:
The degrees of freedom are given by:

The significance level is
and then the critical value can be founded in th chi square table we need a quantile that accumulates 0.05 of the area in the right tail of the distribution and for this case is:

And if the chi square statistic is higher than the critical value we can reject the null hypothesis in favor of the alternative.
Step-by-step explanation:
We have the followign system of hypothesis:
Null hypothesis: 
Alternative hypothesis:

5a + s = 2662
a + s = 1198
4a = 1464
a = 366
5(366) + s = 2,662
1830 adult tickets sold
2662 - 1830 = 832
832 student tickets sold
Answer:
x = 6 y = 5
Step-by-step explanation:
<u><em>X VALUE</em></u>
3x+11 = 5x-1
12 = 2x
x= 6
<em><u>Y VALUE</u></em>
4y-1 = 19
4y = 20
y = 5
