Measures of Central Tendency Pretest 2

Here is the worksheet I provided you on Friday. Please answer the questions in a comment. You can also ask questions about anything you need help on here.

Good Luck

1. State 7 prices, where the median is $3.00, the highest price is $20.00 and the lowest price is $1.00.
2. The mean mark on 4 tests is 78%. What mark is needed on the next test to increase the mean to 80%?

3. Julie buys a book, a game, a puzzle, and a piece of computer software at the book fair. The computer software cost $10. Julie claims that the average price of the items she bought is $2.50. Can she be correct? Why or Why not.

4. Mr. Thompson gave a test to six students who were absent. The highest score was 93 and the lowest score was 65. The mean of the test scores was 79. Create a list of six test scores that satisfy these conditions. Explain why your test scores satisfy these conditions.

5. Find the measures of central tendency for the following data sets:


A) 33, 18, 40, 26, 29, 20, 30
B) 20, 50, 20, 50, 17, 15, 25, 50, 25, 15
C) 15, 20, 80, 75, 5, 50
D) 16, 40, 44, 16, 40, 40, 80, 17, 64, 64, 100

A) If he scores 91 on the next test, which measure of central tendency will be most affected? Explain.

B) If he scores 66 on the next test, Which measure of central tendency will be most affected? Explain.

3. Find the Value of x in the data.

10, 12, 6, 6, 14, x, 8, 10, 12, 12, 8, 14

Is there more than one possible answer for each question?

Mr. Barksalot's Bath Graph

Welcome to your Math Blog. It is a place for you to post answers to questions and to communicate to the world about what happens in 8-17 Math. I would like you to leave a comment answering the following question. Some of this work will have to be done in your math journal. The bold print can be left as a comment.

Bobby fills a sink with enough water to wash his dog Mr. Barksalot. He then puts Mr. Barksalot in the sink and washes him. After he is finished he takes Mr. Barksalot out of the sink. Then he drains the sink.

Draw a graph that represents the level of water in the sink from the time paula started to fill the tub until the tub was empty. Clearly label your graph.

Explain what the graph should look like in a comment on this post AND on the back of your graph.
