Presentation transcript:

1 Mark collected data on the amount of letters in a person’s name and the amount spent on groceries. If he plots the data on a scatterplot, what type of correlation will he most likely see? A. A negative correlation Mr. Wetzel B. No Correlation Ms. Franco C. A positive correlation Mrs. Kelly D. A constant correlation Mrs. Howe

2 Jared collected data on the ages and heights of a random sample of elementary school students. If he plots the data on a scatter plot, what relationship will he most likely see between age and height?   A) A negative correlation grading papers B) No correlation listening to music C) A positive correlation walking a tight rope D) A constant correlation drinking coffee

3 A baseball coach graphs some data and finds the line of best fit. The equation for the line of best fit is y = 0.32x – 20.51, where x is the number of times at bat and y is the number of hits.   How many hits should he expect from a player who is at bat 175 times? A) 35 hits J.J. Watt B) 49 hits Selena Gomez C) 609 hits Luke Bryan D) 62 hits Ludicrus

The number of students who drop out of high school 4 Dr. Champion wants to predict the number of students who will drop out of school so he can get funding for support services.  He determined the equation that represents this data as y = -10x + 216, where x represents the years since 2004, and y is the number of students who drop out. Use this equation to help him predict the number of students who will drop out in 2012? A) 118 students Valentines B) 21 students Friday C) 136 students Saturday D) 156 students Halloween Year The number of students who drop out of high school 2004 217 2005 202 2006 199 2007 185 2008 180 2009 163

5 The scatter plot below shows the average yearly consumption of bottled water by people in the United States starting in 1990. Using the line of best fit, predict the average consumption of bottled water in the year 2000? A) 17 gallons the mall B) 18 gallons the circus C) 20 gallons the arcade D) 19 gallons the rodeo carnival

6 Mr. Van made a graph to represent the time his students spent studying for their test and their actual test score. Which is the correct equation for the line of best fit? (round to tenths place) A) y= 1.4x + 55 cowboy boots B) y= 1.4x – 84 a raincoat C) y= 0.7x + 60 a Strack t-shirt D) y= 0.7x + 56 a football uniform

Which scatter plot best represents the data given in the table? 7 Which scatter plot best represents the data given in the table? A B a clown costume a football helmet C D a pink tutu a clown mask

8 Which graph represents the correlation of its given situation correctly?   A C Temperature Number of people going swimming Size of the dog Amount of dog food purchased doing back flips eating pies B D Number of customers at clothing store Amount of clothing sold Cost of plane ticket Number of tourists flying to Hawaii solving equations juggling

9 A keyboarding instructor at a community college collected data comparing a student’s age and their typing speed. The equation for the line of best fit is given as y = -1.4x + 117.8, where x is the “age in years” and y is the “typing speed.   If your typing speed is 83 words per minute, what is your age in years? (Round to the whole number) A) 77 years old to impress everyone B) 25 years old to win a bet C) 39 years old to show how cool math is D) 11 years old to promote world peace
