Suppose you are investigating the relationship between the variables "Number of customers served each day?"

and "customer type? in store or online ? "

Case 1

	mean	standard deviation	count
in store	1000	200	100
online	900	200	100

p-value 0.000

Case 2

	mean	standard deviation	count
in store	1000	200	100
online	990	200	100

p-value 0.724

a) Comment on the relationship between the two variables in case 1

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
