The t-test Students will practice t-test calculations using technology, just as they will be required to do so during examinations.	TI-Nspire™ CX series TI-Nspire™ CX CAS/CX II CAS	Download182
$17289$ Chi-Square Tests In this activity, students will look at a problem situation that involves categorical data and will determine which is the appropriate chi-square test to use. Standards Textbook	TI-Nspire™ CX series TI-Nspire™ CX CAS/CX II CAS	Download3,700
$17286$ Contingency Tables and Chi-Square This lesson involves deriving and interpreting the chi-square as an indication of whether two variables in a population are independent or associated. Standards Textbook	TI-Nspire™ CX series TI-Nspire™ CX CAS/CX II CAS	Download3,209
Difference in Means This activity involves investigating whether a difference really seems to exist between two sample means. Standards Textbook	TI-Nspire™ CX series TI-Nspire™ CX CAS/CX II CAS	Download3,140
$Statistics_MeaningOfAlpha$ Meaning of Alpha Students will recognize that the alpha value (significance level of a test) is the relative frequency for sample statistic values that lead to a "reject the null" conclusion, given that the null hypothesis is actually true. Students will recognize that a sample mean can lead to a "reject the null" or "fail to reject the null" depending on the alpha level.

$Statistics_MeaningOfAlpha$ Meaning of Power In this lesson, samples are generated from a population for a particular hypothesis test, leading to the conjecture that the null hypothesis is actually false.

$17287$ Resampling This lesson involves approximate sampling distributions obtained from simulations based directly on a single sample. The focus of the lesson is on conducting hypothesis tests in situations for which the conditions of more traditional methods are not met.

$Statistics_Type2Error$ Type 2 Error This activity allows students to experiment with different alpha levels and alternative hypotheses to investigate the relationship among types of error and power.

$Statistics_WhatIsAP-Value$ What is a p-value? This lesson involves beginning with a null hypothesis specifying the mean of a normally distributed population with a given standard deviation.
