Answer:
H0 : p ≤ 0.75 against Ha : p > 0.75
Step-by-step explanation:
We formulate our null and alter native hypotheses as
H0 : p ≤ 0.75 against Ha : p > 0.75
In the question the claim whether the promotional campaign actually increased the proportion of tourists visiting the museum is given which is formulated as alternative hypothesis.
So when we formulate the alternative hypothesis as Ha : p> 0.75 the null hypothesis is H0 p ≤ 0.75
Where p is the probability = 75% = 75/100 = 0.75
Let the number of hours the ski jet was rented be x, then
For company A, Cost = 2.25x + 24
For company B, Cost = 2.75x + 23
Fro the cost to be the same: 2.25x + 24 = 2.75x + 23
2.75x - 2.25x = 24 - 23
0.5x = 1
x = 1/0.5 = 2
x = 2
The cost are the same after 2 hours.
