1 T-obtained is 6.56 and t-critical is 5.45. What is the correct conclusion?

A P> .05; Retain the null hypothesis

BP>.05; Reject the null hypothesis

C P< .05: Retain the null hypothesis

D P< .05; Reject the null hypothesis

2 What is the proper definition for the p-value?

A Probability of the sample data obtained (e.g., sample mean).

B Probability of the population data obtained (e.g.. population mean)

C Probability of the population data obtained (e.g.. population mean) if the null hypothesis is true (e.g..

sample mean is equal to 5).

D Probability of the sample data obtained (e.g.. sample mean) if the null hypothesis is true (e.g..

population mean is equal to 5).

3 What two elements do you need to know to calculate the t-critical value?

A Sample size and mean

B Degrees of freedom and the mean

C Degrees of freedom and chosen alpha level

D Sample size and chosen alpha level
