A psychologist regularly runs rats through a maze and records the amount of time it takes them to finish. One hundred rats were

run through a maze and they averaged 20 seconds with a standard deviation of 5 seconds. Assume that run-times follow a mound-shaped distribution. What can you say about the percentage of rats that took less than 10 seconds to finish?

Answer:

Step-by-step explanation:

  • Given that μ = 20seconds and SD-standard deviation = 5seconds
  • To get the percentage of rats that took less than 10 seconds to finish is;
  • P( X < 10) = P( z < x -μ/SD)
  • = P( z< -2.00) = 0.028 = 2.28%
  • Hence, 2.28% of the rats took less than 10seconds to finish

The height of the cylinder will be 5 units based on the information given.

<h3>How to calculate the height?</h3>

The cylinder has a volume of 45π cubic meters and the radius is 3 units.

The height will be calculated thus:

Volume of a cylinder = πr²h

45π = πr²h

45π = π(3²)h

45π = 9πh

h = 45π/9π

h = 5

Therefore, the height of the cylinder will be 5. units.
