what is the mean for the population of scrores shown in the frequency distribution table?

X f
5 1
4 2
3 3
2 4
1 2

Your sample size is 12 (add up all the frequencies). To find mean, take each X times its respective f, add up these values, then divide by 12.

To find the mean for the population of scores shown in the frequency distribution table, we need to calculate the sum of all the scores multiplied by their corresponding frequencies, and then divide it by the total number of scores.

To get the sum of the scores multiplied by their frequencies, we can multiply each score by its frequency and add up the results. In this case, we have:

5 * 1 + 4 * 2 + 3 * 3 + 2 * 4 + 1 * 2 = 5 + 8 + 9 + 8 + 2 = 32

Next, we need to find the total number of scores. To do this, we sum up all the frequencies. In this case, we have:

1 + 2 + 3 + 4 + 2 = 12

Finally, to find the mean, we divide the sum of the scores multiplied by their frequencies by the total number of scores:

Mean = Sum of Scores * Frequencies / Total Number of Scores
Mean = 32 / 12
Mean = 2.67

Therefore, the mean for the population of scores shown in the frequency distribution table is 2.67.
