Question

4 multiple choice 10 points when a researcher hypothesizes that there is a
eal, non - zero correlation in the population,\ this is commonly referred to as the: alternative hypothesis null hypothesis negative hypothesis regression hypothesis 5 multiple choice 10 points when a researcher makes a specific prediction about the direction of a correlation (for example, a researcher predicts a positive correlation between two variables of interest), the researcher can conduct a directional test, also known as a/an one - tailed test two - tailed test significance test non - significance test

Explanation:

• Question 4: The alternative hypothesis ($H_1$) is a statement that contradicts the null hypothesis. It posits that there is a significant relationship (in this case, a non - zero correlation) in the population. The null hypothesis ($H_0$) would state that there is no correlation ($

ho = 0$). A negative hypothesis is not a standard term in this context, and a regression hypothesis is related to predicting values based on a regression equation, not just correlation.

• Question 5: A one - tailed test (directional test) is used when the researcher has a specific prediction about the direction of the relationship (e.g., positive correlation). A two - tailed test (non - directional) is used when the researcher only predicts that there is a relationship but not its direction. A significance test is a general term for hypothesis testing, and a non - significance test is not a standard term.

Answer:

1. A. alternative hypothesis
2. A. one - tailed test
