Answer: The required sample mode is 41.

Step-by-step explanation: Given that a random sample of 8 students are selected from a class of 45.

The scores of the students on a math test were recorded as follows:

50, 45, 42, 41, 38.5, 39, 40.2, 41.

We are to find the sample mode.

We know that

mode of a sample is the number that occurs more often in the sample.

In the given sample, all the numbers occur once except 41, because it is occurring twice.

Therefore, the mode of the sample is 41.

Thus, the required sample mode is 41.
