To find the mean, we add up all the scores and divide by the number of scores:
Mean = (1+6+7+7+11+13+13+16+11+6+7+13+1+13+16+7+13+16) / 18
Mean = 131 / 18
Mean = 7.28 (rounded to two decimal places)

To find the median, we first need to put the data set in order from lowest to highest:
1,1,6,6,7,7,7,11,11,13,13,13,13,16,16,16
The median is the middle number, so in this case, it is 11.

If we add 24 to the data set, the new data set would be:
1,1,6,6,7,7,7,11,11,13,13,13,13,16,16,16,24
To find the new mean, we add up all the scores and divide by the number of scores:
New mean = (1+6+7+7+11+13+13+16+11+6+7+13+1+13+16+7+13+16+24) / 19
New mean = 155 / 19
New mean = 8.16 (rounded to two decimal places)

To find the new median, we first need to put the new data set in order from lowest to highest:
1, 1, 6, 6, 7, 7, 7, 11, 11, 13, 13, 13, 13, 16, 16, 16, 24
The median is the middle number, so in this case, it is still 11 (since there are now an odd number of scores).
