A. Make a graph about the length of the alligators with the data. Also, write a sentence that describes the graph after making it.][
 * 1.



B. Find out the mean and the median length of the alligators. Mean ( average ): 58+61+63+68+69+72+72+74+74+76+78... = 2124, 2124/25= 84.96 Median: 58, 61, 63, 68, 69, 72, 72, 74, 74, 76, 78, 82, 85, 86, 86, 86... = 85

C. The range is from 58 to 147.

A. Make a graph about the weight of the alligators with the data. Also, write a sentence that describes the graph after making it.
 * 2.

The graph shows me that most of the alligator's weight does not pass through 100, and the heaviest alligator weighs 640 pounds.

B. The mean equals 108.2 (2705/25) The median equals 80

C. It's from 28 to 640.

A.
 * 3.

B. Well, usually, the length of a living creature and it's weight are different from each other. Sometimes, the length is longer than the weight. Sometimes it's that opposite. But most of the times, the weight usually is more heavier than the length, so I'll estimate it a little bit heavier than the weight. i. About 80 inches long. ii. About 90 to 95 inches long. iii. About 170 to 200 inches long.

C. i. 70 inches long- possibly 80 pounds. ii. 100 inches long- possibly 110 to 120 pounds. iii. 130 inches long- possibly 140 to 150 pounds.

D. No, because even if you know the alligator's length, some alligators are more lighter than their length, and some are not. If you make to estimations, one a little bit lower than the length and one higher, maybe that estimate can be near the weight, but it will be still hard.

(1. The mean helps by using the average and figuring out if any of the data is on the average, or is it higher or below. It can describe with details. The median helps too. As same as the average, you can figure out if the data is bigger or smaller than the middle number, median!

(2. The range is the space that the smallest data has to the largest data. With the range, you can figure out the if the data is big or not. ex- 1~9- The range is small. 1000~2500. The range is big.

(3. a. Line plots- Data that doesn't has many out liars, and doesn't has so many data.And the range of it should not be so large. ex- The number of book, drink, food, we read, drink, or eat in 1 week.

b. Stem-and-leaf plot Data that has just one topic. And the range of it should not be so large. ex- The weight of the alligators. The length of the alligators.

c. Coordinate The data that has very small out liars, and the range of it should not be so large. ex- The length of the alligators and the weight of the alligators.


 * 1) 4. The definition of related means to be connected, to be in a same group, or family, in many different ways. So when you say a person's arm span is related to his or her height, it mean a person's arm span is connected, or to be similar. Same for the time it takes to go to the school is related with the distance to school, and the weight of the alligators related with it's length.
