Which story problem could be solved using the division 32 ÷ 8 = 4?

There are 32 mice in 8 groups. How many mice are left?
There are 8 groups, with 4 mice in each group. How many mice are there in all?
There are 8 mice in 32 groups. How many more mice are needed?
There are 32 mice in 8 groups. How many mice are in each group?

d. Cannot be determined with the information provided.

Step-by-step explanation:

Z-score:

In a set with mean and standard deviation , the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Finding the better relative position:

The score with the better relative position is the one with a higher z-score.

To find the z-score, the mean and the standard deviation is needed, and in this question, the standard deviation is not given, and thus, the correct answer is given by option d.
