Using Your TI-NSpire Calculator for Hypothesis Testing: The One-Sample t Test Dr. Laura Schultz Statistics I The one-sample t test is used to test hypotheses regarding population means. This handout will take you through one of the examples we will be considering during class. Consult your lecture notes for more details regarding the non ...

degrees of freedom, which corresponds to the critical value for a 90% confidence interval. In the Results window the value 1.7396067 is shown (Compare this value with the one given by the table in the back of the book). Ex. 2 Suppose we want to find the p-value for t≥2.09 with 4 degrees of freedom. To find this value using STATA type:

Using Excel, Chapter 8: Hypothesis Testing - One Sample Excel alone does not conduct complete hypothesis tests1. However, once you calculate the test statistic, Excel can get the critical values and the P-values needed to complete the test. The functions used to get critical values and P-values are demonstrated here.

Remember 1: When looking-up the proportion in the tail in the Unit Normal Z table, the given p-value is for one-tailed tests. If you have a two-tailed test, as seen in example 1 on the previous page, multiply the given p-value by 2 to reflect the two-tailed nature of the test. Remember 2: SPSS’ p-values are presented as derived from two ...

2. Understand that the actual pvalue (area in the tail past the test statistic) is not found on the ttable. 3. Use a calculator to find the pvalue (part of ttest) 4. Test hypotheses for population means when population standard deviations are not known by applying the ttest.

Calculation of P-Values Suppose we are doing a two–tailed test: • Null hypothesis: = 0 • Alternative hypothesis: ̸= 0 • Give the null hypothesis the benefit of the doubt and assume that it is still the case that = 0. • Now calculate the P–value which is the smallest probability for which we would have rejected the null hypothesis. X. • In terms of the z–distribution (or t ...
