Question

Error (Part 1 of 3)

Suppose you wish to know whether alcohol gel fuel burns at a temperature hotter than 1900 degrees C. You formulate the following hypothesis test:

H0: = 1900 degrees C

H1: > 1900 degrees C

Match the following statements with the type of error they describe.

After collecting a sample, you conclude the gel fuel burns at a temperature above 1900 degrees C, when in fact it burns at a temperature of 1900 degrees C.

Error (Part 2 of 3)

Suppose you are testing whether the ventilation system in a room with several plasma cutters is adequate. In particular, you collect and analyze air samples, finding the concentration of ozone in each sample, and you want to determine whether the ozone concentration in the room is greater than 1 ppm.You formulate the following hypothesis test:

H0: = 1 ppm

H1: > 1 ppm

Which of the following sentences describes a Type II error?

The ozone concentration is 1 ppm, and we decide it is 1 ppm.

The ozone concentration is greater than 1 ppm, and we decide it is 1 ppm.

The ozone concentration is greater than 1 ppm, and we decide it is greater than 1 ppm.

The ozone concentration is 1 ppm, and we decide it is greater than 1 ppm.

Error (Part 3 of 3)

Suppose you are testing rope samples to determine whether the maximum force the rope can sustain before breaking is greater than 1000 lbs. You formulate the following hypothesis test:

H0: = 1000 lbs

H1: > 1000 lbs

Which of the following sentences describes a Type I error?

The rope breaking force is greater than 1000 lbs, and we decide it is greater than 1000 lbs.

The rope breaking force is equal to 1000 lbs, and and we decide it is equal to 1000 lbs.

The rope breaking force is greater than 1000 lbs, and we decide it is equal to 1000 lbs.

The rope breaking force is equal to 1000 lbs, and we decide it is greater than 1000 lbs.
