Asimple random sample of 200 drivers were asked if they drive a car manufactured in a certain country. of the 200 drivers surveyed, 107 responded that they did. determine if more than half of all drivers drive a car made in this country.

More than half of all drivers drive a car made in this country is a TRUE statement.

Step-by-step explanation:

The total drivers in the random sample  = 200 drivers

The number of drivers who drive the car created in the country =  107 drivers

Let us find the half of the drivers in the sample space.

⇒

⇒ The half number of drivers in the sample space =100

But due to the given data,

The number of drives who drive the car created in the country is 107.

Also, 107 > 100

⇒ The number of drives who drive the car created in  the country  >  The half number of drivers.

Hence, more than half of all drivers drive a car made in this country is a TRUE statement.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
