Find the χ2 statistic
Solution
The formula for calculating χ2 statistic is given by ;
χ2∗ =∑(Oi−Ei)2/Ei, where Oi and Ei is the i^th observation and the i^th expected count
From the given data calculated the expected count using the formula; E = (row total *column total)/sample size
χ2 = 7.104439336,
χ2 = 7.104 (rounded to 3 decimal .places)
The P-value is;
Degrees of freedom = (2-1)*(2-1) = 1, χ2 = 7.1044
P-value from chi-square calculator is 0.007689

Contribution margin should increase by 10.29% and operating profit would increase by 16.81%.
Explanation:
since the information is not complete, I looked it up:
Revenues
13,500 passengers:
8,100 x $23 = $186,300
5,400 x $15 = $81,000
total $267,300
variable costs:
fees paid to the city 10% of total revenue
souvenirs $0.55 per passenger
brokerage fees 60% of total tickets x $1.40
carriage drivers $3.90 per passenger
fixed costs:
depreciation $2,900
