A hypothesis test needs to be run for the mean of a population that is normally distributed. If σ is known, what distribution is used for the test and what variable is used to write the hypotheses? (Choose one distribution and one variable.)

A hypothesis test needs to be run for a population proportion. The sample taken for the test has more than five successes and more than five failures. What distribution is used for the test and what variable is used to write the hypotheses? (Choose one distribution and one variable.)

A discrete random variable, X, can take on the values x=1, 2, 3, …, 9, 10. Match each of the following probabilities with an equivalent statement.  

What are the null and alternative hypotheses used to test for a statistically significant linear correlation. 

A total of 130 people had their body temperature tested. The subjects were grouped based on if they were men (M) or women (W) and if they had a high (H) or low (L) pulse rate. This gives four groups of people: MH, ML, WH, WL. What distribution (and degrees of freedom) would be used to test if mean body temperatures for these four groups are equal?

The correlation coefficient, r, can be used to decide if data has a strong linear relationship. We always have -1≤r≤1{“version”:”1.1″,”math”:”-1≤r≤1″} .  What values of r  indicate the strongest linear relationship to the data. (Select all statements that indicate a strong linear relationship.)
