Answer:
Null hypothesis: ∪ₐ = ∪ₓ
Alternative hypothesis: ∪ₐ ≠ ∪ₓ
Step-by-step explanation:
Null hypothesis: ∪ₐ = ∪ₓ
Alternative hypothesis: ∪ₐ ≠ ∪ₓ
where ∪ₐ represents mean of sample of new cars and ∪ₓ represents mean of sample of older cars.
Using a difference in means t test will help determine if new owners tune up their cars more frequently than older car owners.

To solve this problem you must apply the proccedure shown below:
1. You must apply the formula for calculate the arc length, which is:
arc length=(angle)(radius)
2- As you can see, <span>the circle has a radius of 5 yards and the angle subtended by the arc measures 1 1/2 radians. Therefore, you have:
</span>
The angle is:
1 1/2 radians=1.5 radians
3. When you susbtitute these values into the formula, you obtain:
arc length=(1.5 radians)(5 yards)
arc lenght=7.5 yards
4. Therefore, the answer is: 7.5 yards.
