Let's first write down the values that we have in number form.

2,3,4,4,5,5,5,6,6,6,7,7,7

b. The median is the middle number of the data set

2,3,4,4,5,5,5,6,6,6,7,7,7

Since 5 is the middle number, 5 is the median
Answer=5

c. the mean can be calculated by adding all of the numbers, and then dividing by the number of numbers.

Mean=(sum of all numbers)/(number of numbers)

Sum of all number=2+3+4+4+5+5+5+6+6+6+7+7+7=67
There are 13 numbers in the data set

Mean=67/13=5.15
Answer=5.15

c. if a data point of 20 were to be added to the data set. The median would only increase from 5 to 5.5

2,3,4,4,5,5,5,6,6,6,7,7,7,20   (5+6)/2=11/2=5.5

The mean would increase the most from 5.15 to 6.2

Mean=(2+3+4+4+5+5+5+6+6+6+7+7+7+20)/14=6.2

In general, outlying numbers in a data set have a greater effect on the mean than the median.

She should use 12/3 to measure

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
