A newspaper reporter wants to know how popular the hobby of bird watching is in the city. He asked people at the local bird refuge if they watched birds as a hobby. Which of the following best explains whether the reporter's data is valid or not?
A. The data is valid for the entire city because the bird refuge is located in the city.<----------
B. The data is not valid for the entire city because people can have more than one hobby.
C. The data is not valid for the entire city because bird watchers are more likely to visit a bird refuge.
D. The data is valid for the entire city because a bird refuge is a good place to find people who like to watch birds.

I disagree.

Oh okay my second choice would be D

• math HELP!!!!!! -

no

• math HELP!!!!!! -

Okay i got it C

• math HELP!!!!!! -

No.

You want to know how many people in the city watch birds. The reporter's data is not valid because he's only surveyed bird watchers. He's ignored the 90% or so of the people who don't go to the bird refuge.

C is correct.

I just hit finish on the test. These where the answers. 100%! There are also some other questions I will give my answer for. Please do NOT copy my answers. Change them up a bit because the teacher will know you copied.

19.
A. It is misleading because 3.8 and 4.6 are added into the graph. Since those two numbers are added, it makes the graph bigger and misleading.
B. You can redraw the graph by removing 3.8 and 4.6.

20.
A. Mean: 78.1, Median: 81, Mode: 59.
B. Because the mode has the smallest number, the social studies teacher should use mode to help her be convinced to study more.

21.
A. 50 turtles were caught in 2009.
B. 30 turtles were caught in 2010.

22.
A. Both sets are ranged 51-83. Set A is higher and set B is lower.
B. The mean is 70 for both soil A and B.
C. 71.9

Questions 18-22 have not been graded. You do not have to write what I wrote. Also, if you don't trust my answers, have fun not getting 100... I don't know what else to say. Unless your a math wiz. If you where a math wiz, why would you be looking up answers??

Okay well I just got my test answers. I completely BOMED that test. I got all of the essay questions wrong. Here are the real answers:

19.
A. The graph could be misleading because the vertical scale uses very small intervals and starts at 3.8, which makes the changes seem greater than they really are.
B. The graph could be redrawn with its vertical scale starting at zero and with larger intervals.

20.
A. Mean: 78, Median: 80.5, Mode: 58. (My teacher did not reply on B so i'm guessing its right.)

21. A. 125 turtles. B. 150 turtles.

22.
A. All but the lowest value for Soil B and the highest value for Soil B fall within the same range.
B. Soil A: 71.8. Soil B: 75.
C. Soil A: 8.16, Soil B: 5.4.
D: The heights of the sunflowers planted in Soil A are more variable because the means of the heights in each group are about the same, but the mean absolute deviation for Soil A is greater.
