B. what is the mean and what is the median?

C.the mean is 84.98in and the median is 86in

2. make a graph on the alligators weight.

this is my data for the alligators weight bellow.



and this is my graph.

most of the gators are below 100 pounds, and there are three outliers.

b. what is the mean median?

the mean weight is 114 bl, the median weight is 80 lb.

c. what is the range?

the range is 28 to 640 bl.

3.

A. make a coordinated graph of the length and the weight of the gators.

this is the data i use from the textbook chart below.



this is my coordinated graph below. a.

b. what relationship do you notice between length and weight of the gators that are

i. 61 and 63 inches long? ii. 82, 85, and 86 inches long? iii. 90, 94, and 114 inches long?

i. The gator that is 63in is two inches longer than the gator that is 61 inches long but the gator that is 2 inches longer than the other is ten pounds liter. ii. they have a similar weight to there length (in the 80's). iii. all of they weights are in the hundreds.

C. what weights would you predict for an alligator that is... 70 inches long? my guess would be 65 pounds 100 inches long? my guess would be 140 pounds 130 inches long? my guess would be 190 pounds

d. Yes i do think you can made a good estimated guess of a gators weight by knowing its length.

1. The mean and median help you describe a set of data because with the mean you know the set of data should be around that area and you know with the median what's in the middle of the graph. 2. The range helps you describe a set of data so that you know what the highest and lowest and you know nothing is out of that range. 3.what kinds of numerical data are best dispelled with...

line plot: how many times the class can jump at one time. stem and leaf plot: the time it takes for the class to get to school coordinate graph: ....... the lengths and weight's of 25 alligators

4. what dose it mean that a gators weight's is similar to it's length?

It sort of mean's in one way they'er perfect that they have the same length as their weight.
