Test Tomorrow!

Tonight...study! Tomorrow we have a test for our first grade of the third quarter! The test is 25 multiple choice questions. The topics are listed below. You can use a graphing calculator throughout.
(The four bullets in italics represent the 4 questions you have not learned how to do yet. These will not be counted toward your grade).
  • Find the mean of a sample
  • Find the median of a sample
  • Find a basic probability (Ex: Find the probability the spinner lands on blue.)
  • Find probability using "AND," "OR," etc. (Ex: Find the probability you spin a spinner 3 times and all 3 spins are red._)
  • Find a probability using "AND," "OR" without replacement (Ex: There are 10 people to be selected for a field trip, 6 males, 4 females. Find the probability that we select two people and they are both males.)
  • Use a regression equation to make a prediction (substitute for x!)
  • Identify the shape of a distribution
  • Use z-scores to compare two different test scores
  • Find the overall mean given information about 2 samples (Multiply each sample mean by the size of the sample; then, add these answers/products; then, divide this sum by the total number of people)
  • Evaluate potential conclusions drawn from a study
  • Understand how summary statistics (mean, median, mode, range, variance) are affected by outliers
  • Read a scatterplot
  • Estimate the correlation of a scatterplot
  • Identify the explanatory, response variable in a study
  • Create a confidence interval
  • Identify which type of hypothesis test/interval should be used
  • Find the percentile (% left) for a given value using a Normal model
  • Evaluate a study
  • Interpret slope
  • Interpret p-value
  • Know the measures of center and spread
  • Find expected value
  • Calculate a p-value
  • Know which type of data collection allows us to determine cause and effect
This weekend your homework will be the chapter 12 reading questions...you can find these in one of the posts below (or you got them in class today). Feel free to get a head start on your homework!
