Answer:

mean <median <mode

Step-by-step explanation:

We must calculate the measures of central tendency, which are the mode, the mean and the median.

fashion, value that is most repeated, in this case 87

median, the mean value, how is an even number, the mean is the average of these central numbers, in this case it is 82 and 87

(82 + 87) / 2 = 84.5

average, is the average of all the data, we calculate it like this:

(60 + 74 +82 +87 +87+ 94) / 6 = 80.66

Therefore, the relationship would be like this:

mean <median <mode

When we make inferences about the difference of two independent population proportions, what assumptions do we need to make? mar
Elis [28]

When we make inferences about the difference of two independent population proportions, we assume that it is a random sample, and the number of successes and failures are at least 15 in each group.

Two independent proportions tests involve comparing the proportions of two unrelated datasets.

For these two datasets to be regarded as an independent population, the following must be true or assumed to be true

  • The datasets must represent a random sample
  • Each dataset must contain at least 15 successes and failures

Hence, the above highlights are the assumptions of two independent population proportions.
