Question

A user plugs a smartphone into portable speakers and plays a song, but the song is not heard. Indicate whether the test result validates or invalidates the hypothesis.

Hypothesis: Volume switch on smartphone is off.

Test: Check if smartphone's volume switch is off. Off?
Result: Yes (volume switch is off).
Question 2 options:

Validates


Invalidates

Answer 1

The test result indicates that the volume switch on the smartphone is indeed off. Since the hypothesis states that "the volume switch on smartphone is off," and the test result confirms that it is off, this supports the hypothesis.

Thus, the correct option is:

**Validates**
