Answer:
The sampling distribution of the mean will have no unit.
Explanation:
Given that:
P(B) = 0.62
P(C) = 0.71
pˆB = 0.70
pˆC = 0.75
The expression : pˆB−pˆC
Represents the difference in mean of the sample distribution :
The proportions pˆB = 0.70 and pˆC = 0.75 are obtained as (number of workers who purchased coffee / total number of workers). The ratio above due to division will have no units.
