The ______, symbolized by H0, is a statistical hypothesis that states that there is no difference between a parameter and a specific values, or that there is no different between two parameters.

• Null Hypothesis

• Alternative Hypothesis

A researcher studies gambling in young people. She thinks those who gamble spend more than $30 per day. Select the correct alternative hypothesis.

We reject the null hypothesis when it is true. This would be an incorrect decision and would result in a type _ error.

If n<30, and the variable is normally distributed with a standard deviation, which test do you use?

• z- score

• t-score

• Chi-squared

Should the null hypothesis be rejected if α=0.05 and p-value=0.027?

• reject null hypothesis

• do not reject null hypothesis
