I suspect my corner pub of short-changing its customers. Over the course of 20 very scientific visits, I order a total of 50 pints (1 pint = 568 mL). I measure each one exactly with a volumetric flask. The average volume per 'pint' is 558 mL, and the standard deviation is 5 mL. I decide to conduct aone-sidedhypothesis test.

Which is the null hypothesis of my experiment?

Group of answer choices

a) The pub really does maintain a true average of 568ml per pint.

b) The pub is fair or generous and (on average) pours at least 568mL per pint.

c) The pub is fair or stingy and (on average) pours no more than 568mL per pint.

d) I have no idea what the true average pour at this pub is, except that it's not 568mL per pint.

Which is the alternative hypothesis of my experiment?

Group of answer choices

a) The pub is fair and pours (on average) exactly 568mL per pint.

b) The pub is generous and pours more than 568mL per pint.

c) The pub is stingy and pours less than 568mL per pint.

d) I have no idea what the true average pour at this pub is, except that it's not 568mL per pint.

Would you reject the null hypothesis? Feel free to use your intuition, random number generation, or statistical theory.

Group of answer choices

a) Yes, I would reject the null hypothesis.

b) No, I would fail to reject the null hypothesis.
