Suppose you are investigating the relationship between the variables "The amount of alcohol purchased in a single order ?"

and "Location? Sydney or Brisbane "

Case 1

	mean	standard deviation	count
Brisbane	$30	$10	10
Sydney	$40	$15	10

p-value 0.22

Case 2

	mean	standard deviation	count
Brisbane	$30	$10	100
Sydney	$40	$15	100

p-value 9E-05

a) Comment on the relationship between the two variables in case 2

b) Explain what that p-value is measuring and why the p-value in case in 1 is different to the p-value in case 2

c) Make a conclusion based on the p-value in case 2
