Problem 1a: Make an appropriate graph for the lengths of the 25 alligators and then write a sentence that describes the distribution of lengths shown in the graph.

Problem 1b: For these data what are the mean and median lengths?
 * = Gator number ||= Length ||
 * = 1 ||= 74 ||
 * = 2 ||= 94 ||
 * = 3 ||= 85 ||
 * = 4 ||= 61 ||
 * = 5 ||= 128 ||
 * = 6 ||= 72 ||
 * = 7 ||= 89 ||
 * = 8 ||= 90 ||
 * = 9 ||= 63 ||
 * = 10 ||= 82 ||
 * = 11 ||= 114 ||
 * = 12 ||= 69 ||
 * = 13 ||= 86 ||
 * = 14 ||= 88 ||
 * = 15 ||= 58 ||
 * = 16 ||= 90 ||
 * = 17 ||= 94 ||
 * = 18 ||= 68 ||
 * = 19 ||= 78 ||
 * = 20 ||= 86 ||
 * = 21 ||= 72 ||
 * = 22 ||= 74 ||
 * = 23 ||= 147 ||
 * = 24 ||= 76 ||
 * = 25 ||= 86 ||

The median for this data is 85 and the mean is 84.96.

Problem 1c: For these data what is the range of lengths?

The range is from 58 to 147.

Problem 2a: Make an appropriate graph for the weights of the 25 alligators and then write a sentence that describes the distribution of lengths shown in the graph.

Problem 2b: For these data what are the mean and the median?
 * Gator Number || weights ||
 * 1 || 54 ||
 * 2 || 110 ||
 * 3 || 84 ||
 * 4 || 44 ||
 * 5 || 366 ||
 * 6 || 61 ||
 * 7 || 84 ||
 * 8 || 106 ||
 * 9 || 33 ||
 * 10 || 80 ||
 * 11 || 197 ||
 * 12 || 36 ||
 * 13 || 83 ||
 * 14 || 70 ||
 * 15 || 28 ||
 * 16 || 102 ||
 * 17 || 130 ||
 * 18 || 39 ||
 * 19 || 57 ||
 * 20 || 80 ||
 * 21 || 38 ||
 * 22 || 51 ||
 * 23 || 640 ||
 * 24 || 42 ||
 * 25 || 90 ||

The median is 80 and the mean is 102.2.

Problem 2c: For these data what is the range?

The range is from 28 and 640.

Problem 3a: Make a coordinate graph showing the length and weight data.

Problem 3b: What do you notice between length and weight of alligators that are

i. 61 and 63 inches long. The relationship is that for the weight the first and the last number is the same. ii. 82, 85 and 86 inches long. The relationship is that the length and weight are quite close. iii.90, 94 and 114 inches long. The relationship is that the length and weight are quite far away.

Problem 3c: What would you predict the weight of an alligator that is i. 70 inches long. 51 pounds. ii.100 inches long. 150 pounds. iii.130 inches long. 370 pounds.

Problem 3d: If you know an alligators length would you know the alligator's weight? Make a good estimate.

I think you would but aproximatly because normally the length and the weight are very close but there are sometimes that they are not very close.

Explaining your reasoning.

1:In the data set how do the mean and median help in describing the numbers? They describe by telling you what the middle is and what the average is. 2:In the data set how does the range help in describing the numbers? It describes by telling you which number is the smallest and which number is the largest. 3: What is the best way numerical data to be displayed? Stem and leaf plots. 4:What does it means to say that the weight of an alligator is related to its height or that to say a person's armspan is related to his or her height or to say that the time it takes to school is related to the distance traveled? It means that how its similar and how's it difference.
