Can we develop a hypothesis/procedure to find a missing value in a set of data given a mean?2. How can we test our hypotheses to ensure that our procedure works for similar scenarios? Date: ____________ Let’s take a sample of the heights of people (in inches) in this class together:Identify the type sampling method that we just performed, and explain how you know.Is there any bias with the sample that we took, and explain?Identify the data that we collected as qualitative, quantitative discrete, or quantitative continuous.Calculate the mean height of this sample (our class) using your calculator.Calculate the standard deviation using your calculator.Uh oh! We forgot about someone!We forgot about ________________________. Even worse, _________________________ was up all last night watching the game, and has no voice so we can’t ask them. However, Mr. Roberts calculated the mean including them. The new mean is now: _________________ with ____________ data pointsYour task:Using your previous notes, classmates, and knowledge of statistics, determine and write out a procedure to determine the missing height! Make sure to test that it works! Using your procedure, show that it works with our data. Helpful hints for determining a procedure:Re-read the scenarioWrite down things that you know about the problem. Compare and contrast the original mean to our new meanLook back at previous lessonsAsk each other questions, and maybe test a classmate’s procedure to make sure it worksTry calculations using different methods (by hand, calculator, etc.)-15948824952500Use the space below to try to figure out a procedure to find the missing height:-9558920696500Check in with me when you are confident in your answer to receive feedback on your answer1052623-1132700Write-up: Name:____________________________Use the space below to write the procedure you found that works for our class example:Advice:Numbering or bulleting the steps might be helpfulAsk a classmate to read your procedure to see if they can follow along2-7 Follow up tests:Name:________________________Directions: Using the procedure you have found, try answering the following IB questions to determine if your procedure works. An IB Math Studies student, Matt, has the following test scores for the first quarter:84, 98, 79, 82, 93Matt wants to make sure that he gets an average of 86 for the quarter. He has one more test to take. What score must Matt receive on the last test of the quarter in order to earn an average of 86?The mean of the ten numbers listed below is 6.2. 1, 3, 10, a, 5, 6, 7, 5, a, 9 Find the value of aMixed Practice of Unit 2:Classify the following data as qualitative, quantitative discrete, or quantitative continuous: The number of sweets in a packetThe heights of students in the junior class.The weight of 20 puppiesThe number of red cars in the parking lot. The time is takes to swim 100 metres.The numbers of games played in each set of a tennis tournament were9, 7, 8, 11, 9, 6, 10, 8, 12, 6, 8, 13, 7, 9, 10, 9, 10, 11, 12, 8, 7, 13, 10, 7, 7.Calculate the mean number of games played per set.What is the modal number of games?(c) Create a boxplot for these games. 3714751701800(d) Write down the maximum number of games played and determine if it is an outlier. ................
