T test for 2 independent means: Instructions: Test the claim that the mean for your quantitative variable I is the same as the mean for the quantitative variable 2, using a significance level of 0.05. Claim: P = P 2 variable 1 variable 2 26 2950 21 1900 45 45 Hypothesis Clearly write the null and alternative hypothesis. He: PI = P 2 H: H1 7H 2 a = 0.05 Ti83/Ti84 input: Type in the values you used to find the test statistic and p-value on your ti83 or ti84 calculator in the space below. Do not use rounded values in your computations! 2-Samp TTest Inpt: Data Stats * = 26 Sx, = 21 n, =45 I, = 2950 Sx, = 1900 n,=45 Pooled: No Yes Calculate Draw Results: Test statistic: t = ? P-value: p = ? Interpretation Decision: (Translation: Should you reject, or fail to reject H ?) Informal statement: (Translation: Is the test statistically significant?) Formal statement: (Hint: You should be using something like: There is/isn't sufficient evidence to warrant rejection/support the claim that...)
