:Explain the relationship between hypothesis, tests, and population mean.

Instructions:Read the following and answer the questions.

Directional versus nondirectional hypothesis testing.Cho and Abe (2013) provided a commentary on the appropriate use of one-tailed and two-tailed tests in behavioral research. In their discussion, they outlined the following hypothetical null and alternative hypotheses to test a research hypothesis that males self-disclose more than females:

H0: males females 0

H1: males females> 0

1.What type of test is set up with these hypotheses, a directional test or a nondirectional test?Directional

2.Do these hypotheses encompass all possibilities for the population mean? Explain. ____________________________________________________

Problem Set 3.4:Hypothesis, Direction, and Population Mean

Criterion:Explain decisions for p values.

Instructions:Read the following and respond to the prompt.

The value of apvalue.In a critical commentary on the use of significance testing, Lambdin (2012) explained, "If ap< .05 result is 'significant,' then ap= .067 result is not 'marginally significant'" (p. 76).

Explain what the author is referring to in terms of the two decisions that a researcher can make._________________________________________________

:Identify IV, DV, and hypotheses and evaluate the null hypothesis for an independent samplesttest.

Data:Use the information from Problem Set 3.5.

Instructions:Complete the following:

a.Identify the IV and DV in the study. _____________________________________

b.State the null hypothesis and the directional (one-tailed) alternative hypothesis. ___________________________________________________

c.Can you reject the null hypothesis at = .05? Explain why or why not. ___________________________________________________
