Question:
As your textbook indicates, computer software frequently provides the p-value associated with a specified t test value. Microsoft Excel was used to obtain the one-tailed and two-tailed p-values shown in the items below. These p-values are for independent t tests that were carried out to investigate a difference between an experimental group and a control group. For each, indicate whether the result would be statistically significant with alpha equal to .05 for a one-tailed test and for a two-tailed test.
1. One-tailed p-value = 0.267006; two-tailed p-value = 0.534011
2. One-tailed p-value = 0.176499; two-tailed p-value = 0.352999
3. One-tailed p-value = 0.000112; two-tailed p-value = 0.000223
4. One-tailed p-value = 0.002699; two-tailed p-value = 0.005399
5. One-tailed p-value = 0.040598; two-tailed p-value = 0.081196
