Use: Use: King Henry Died _ Drinking Chocolate Milk Know what is contained in each of the number sets: reals, rationals, irrationals, integers and natural numbers. Know what is contained in each of the number sets: reals, rationals, irrationals, integers and natural numbers.

Studying for the test. For chi-squared, if your value of chi-squared is greater than the CRITICAL VALUE you reject the null hypothesis. For chi-squared, if your value of chi-squared is greater than the CRITICAL VALUE you reject the null hypothesis. For p-values, the opposite is true. If your p-value is less than the SIGNIFICANCE LEVEL, you reject the null hypothesis. For p-values, the opposite is true. If your p-value is less than the SIGNIFICANCE LEVEL, you reject the null hypothesis.

Studying for the test. Remember that a linear regression always goes through the mean point Remember that a linear regression always goes through the mean point The derivative is = 0 at a maximum or minimum!!! The derivative is = 0 at a maximum or minimum!!!

CALCULATOR DIRECTIONS When using substitution into a formula, use ( ) around numerators/denominators When using substitution into a formula, use ( ) around numerators/denominators Make sure you can find the intersection of two graphs with the calculator Make sure you can find the intersection of two graphs with the calculator CALC (2 nd TRACE  option 5) CALC (2 nd TRACE  option 5) Make sure you know how to find maxes and minimums using a calculator. Make sure you know how to find maxes and minimums using a calculator. CALC (2 nd TRACE  option 3 or 4) CALC (2 nd TRACE  option 3 or 4)

CALCULATOR DIRECTIONS Make sure you know how to use the calculator stat functions. Make sure you know how to use the calculator stat functions. STAT  Edit STAT  Edit STAT  CALC  STAT  CALC  1-Var Stats for L1 1-Var Stats for L1 2-Var Stats for L1 and L2 2-Var Stats for L1 and L2 LinReg for linear regression LinReg for linear regression Use linreg for r as well! Use linreg for r as well! Know how to run the chi-squared test in the calculator. Know how to run the chi-squared test in the calculator. MATRIX  Edit (put in table without totals) MATRIX  Edit (put in table without totals) STAT  TESTS  X 2 - Test… STAT  TESTS  X 2 - Test…

CALCULATOR DIRECTIONS Normal Distribution functions! Normal Distribution functions! DIST (2 nd VARS) DIST (2 nd VARS) normalcdf(lower, upper, mean, sd) normalcdf(lower, upper, mean, sd) Use when given a % in the probelm: Use when given a % in the probelm: invnorm(% to the left & out of % form, mean, sd) invnorm(% to the left & out of % form, mean, sd)

Before the test. Sleep well the night before. Sleep well the night before. Eat breakfast. Eat breakfast. Eat lunch. Eat lunch. Be hydrated, but not so much that you float away. Be hydrated, but not so much that you float away.

During the test. Your calculators have been cleaned out! Your calculators have been cleaned out! Make sure you are in degree mode. Make sure you are in degree mode. Make sure your diagnostics are turned on. Make sure your diagnostics are turned on.

During the test. Start each problem on a new page. Start each problem on a new page. In Paper 1, always write the full answer before rounding in the working box. In Paper 1, always write the full answer before rounding in the working box. Looking at point values…low point values on Paper 2 items imply use of the calculator. Looking at point values…low point values on Paper 2 items imply use of the calculator.

During the test. If you don't know an equation/answer...make it up. Finish the problem using the made up equation. If you don't know an equation/answer...make it up. Finish the problem using the made up equation. Look at the problem: “Show that” means they want you to get that answer. And that answer will most likely be used in future parts. Look at the problem: “Show that” means they want you to get that answer. And that answer will most likely be used in future parts.

During the test. Graphing: label the axes! Graphing: label the axes! Make sure you know what a cm is on our graph paper. Make sure you know what a cm is on our graph paper. Use the appropriate scale given in the problem. Use the appropriate scale given in the problem. Make sure you “show your work” on the graphs if you get information from the graph. Make sure you “show your work” on the graphs if you get information from the graph.

During the test. If you must draw a Venn Diagram remember to label the Universal Set! If you must draw a Venn Diagram remember to label the Universal Set! Pace yourself! When you read the exam make a strategy for how you want to attack the problems. Pace yourself! When you read the exam make a strategy for how you want to attack the problems.
