Regression slope intervals | For example, are the conditions for a regression slope confidence interval met? |

Regression slope test | For example, interpret the p-value that comes from a regression slope test. |

Sampling distributions | For example, find the mean and standard deviation of 100 randomly selected babies from a population normally distributed with a mean of 7.5 pounds and standard deviation of 1.25 pounds. |

Scatterplots & correlation | For example, match correlation coefficients to scatterplots. |

Skill check: Strong acid/strong base titrations | Check your understanding of strong acid and strong base titrations! |

Transforming and combining random variables | For example, find the variance of the difference between the running times of two students selected from a population with mean 8 minutes and standard deviation 50 seconds. |

Two sample intervals for proportions | For example, if a professor wants a 90% confidence interval with a margin of error no more than 0.08, how large should his sample be? |

Two sample tests for proportions | For example, given a context, what is the correct interpretation of the p-value? |

Two sample tests for means | For example, when do you need to check sample distribution for skewness or outliers before running a two-sample test about the mean? |
