Math 116A - Assignment for February 11 – at most 5 hours

1) Complete the handout given out in class (4 PAGES – may take between 30 to 60 minutes)

2) STATISTICS: You are going to study on your own the material from sections 2.1 and 2.2. It’s simple material – I know that as a college student you can handle this on your own.

Having the study guide handy will help you. As you study, check what you know and put a ? on what you don’t understand to come back again later. The study guide lists all the vocabulary you have to learn.

3) If you don’t have the study guide, go to my website and get into the STATISTICS page

On the yellow row, under Chapter Documents you find the study guide for chapters 1 and 2 (I gave you this document already, if you don’t have it, print it)

Chapters 1 and 2 Study Guide

4) How do you handle this? Read the definitions in the book, read the examples, OR, use the power point presentations of our book for these two sections. They are in my website: STATISTICS PAGE, pink row – first cell (4th row from the top)

Power Point Presentations / Current Population Survey - CPS / How to Study
Read

5) After reading the material, go to MyStatLab and work on STATISTICS, sections 2.1 and 2.2. Bring your questions to class.

6) The average of these two sections will be recorded as a quiz grade at the closing time: 6 am on Monday morning

7) On Monday, working in groups, you will use all those concepts learned in 2.1 and 2.2 to construct graphs with the data you provided last week.

Turn the page for more

8) PAPER DUE: WRITING ABOUT MC STUDENTS – DATA FROM OIRA, where there is all the info you enter in the college application.

Go to my website, STATISTICS page, on the first green row, first cell, click on the OIRA link

OIRA - MC data

On the left column of the OIRA page, click on STUDENT DATA. On the center, click on 2012 FALL PROFILE.

a) Go to page 5, and write FIVE statistics and FIVE parameters, anything that interests you. Clarify what data you are describing: for example: there are 25 American Indian students taking classes in MC Germantown (this is a statistic – from a sample)

b) For the RACE category, lists the categories and the percentages (for Rockville)

c) go to page 8 – summarize the enrolment by age and enrolment by gender

d) What is the name of the graphs in page 9, 11, 13, 21? For each graph, indicate the variable and classify it as quantitative or categorical. If appropriate describe shape.

February 4, 2013

  • We reviewed the algebra material
  • We completed the Statistics handout in 2.1 and started on the 2.2 handout
  • Finish the 2.2 handout for next class – TO TURN IN!!!
  • I RECORDED a grade out of MML – from 12 assignments, the average was recorded
  • MML assignments are again available – finish them!
  • THERE is a new stats assignment
  • When you complete all of the assignments on lines, go to my website and work on the problems from the videos
  • EXAM 1 – FRIDAY 2/8 – LINEAR FUNCTIONS
  • TEST DETAILS FOLLOW:

Math 116A – Study Guide for EXAM I – LINEAR FUNCTIONS – FRIDAY FEBRUARY 8

  • NEWS ABOUT TEST
  • Please, DO NOT miss the test, no make-ups will be given
  • I’ll be in class by 7:45 am. You are welcome to come at that time to start the test
  • You will have until 9:25 a.m. to finish the test. I will not extend the time, please, do not come late!!!
  • All problems in the test are story (word) problems.
  • Read carefully, and respect the instructions given in the problems. If they say YEARS SINCE ______, the x-values count the number of years after the given base year
  • Round as indicated, otherwise you will lose a point (make sure you round correctly!!!)
  • If the round-off rule is not specified in the problem, use your criteria – no points will be deducted
  • Statements like this will appear on your test:

Use a complete sentence and correct units to interpret in context.

All interpretations should be given in context with correct units

  • Statements like this will be in your test:
  • Algebraic steps should be shown in parts b and c

If algebraic steps are required, show them. You will only be given one point for a correct answer which is not supported by algebraic process; the remaining points will be lost.

  • If algebraic work is not required, points will not be deducted if correct answers are given without supporting work

Linear Functions F(x) = mx + b – study guide

  1. One problem will have the mathematical model already given and many questions will be asked (see item 4 below)
  2. In one problem you will have to show the algebraic process of finding the equation of the line going through two points (you don’t get any points if you use the linear regression feature of the calculator)
  3. In another problem you will be given data and asked to do the following:

a) Sketch a scatterdiagram and label axes with variable names and units

b) Use the regression feature of your calculator to find the equation of the best model that fits the data

  1. Once you have the linear model y = mx + b or f(x) = mx + b you should be able to answer all the following question types.
  2. Identify the independent variable and the units
  3. Identify the dependent variable and the units
  4. Create a table of values
  5. Graph
  6. Identify slope and interpret in context
  7. Interpret the slope as an average rate of change
  8. Interpret the slope as a rate of change
  9. Find the y-intercept and interpret in context
  10. Find the x-intercept and interpret in context
  11. For a given x, find y and interpret in context
  12. Find F(#) (this is the same as saying, if x = #, find y)
  13. For a given y, find x, and interpret in context
  14. Solve F(x) = # (this is the same as saying, if y = #, find x)
  15. Interpret in context the coordinates of a point that satisfies the equation

(a, b) or f(a) = b

February 1

  • My web address is on the syllabus (or google MARIA ARONNE)
