The critical value of t * is such that the area under the t -distibution with df= n M + n F -2 between -t * and t * is equal to the confidence level. Students may have to use a t critical value table from a textbook to determine the appropriate critical value. For the example data in Table 1, the resulting confidence interval would be as follows:

Area is almost the same as the confidence level –but you have to add one tail to get (in essence) the right limit, or critical T-value. For example, find the critical value of …

Critical value: z* = 1.96. 95% Margin of Error: C% confidence interval for a population proportion p is. Answer:-.032(0.008 or (-0.040, -0.024) Two-proportion z-test. Assumptions. Random samples, each with independent observations. Independent samples. If sampling without replacement, the sample size n should be no more than 10% of the population.

Calculate and interpret a confidence interval for the difference between two means. Use the two-sample t statistic with conservative degrees of freedom if you do not have statistical software. Use the TI-83/84/89 or software if you have it. Test the hypothesis that two populations have equal means against either a one-sided or a two-sided ...

Another way you could do this would be Statistics>Summaries, tables, & tests>Classical tests of hypotheses> Two-sample variance comparison calculator. The p-value is 0.6956 so we fail to reject Ho. Question 5: Perform the appropriate test to test whether there is a difference between the following variances: s21 = 99, s22 = 40, n1 = 100, n2 = 20

If the value of p (found at the same time on the calculator with X2) is smaller than the sig. level (remember, the %), then the null hypothesis can also be rejected. So, Reject Ho because Sig. level > p. Accept Ho because Sig. level < p. So, the two ways to reject the null hypothesis are if . 1.) X2 calc > X2 critical, or. 2.) Sig. level > p ...
