It is c. that is because there are 10 red to 20 black which is a 10:20 ratio. you can simplify this to 1:2 since they are both divisible by 10
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.
Hi, thank you for posting your question here at Brainly.
In order to answer this question, you must have data for the electricity cost. For this example let's follow the electricity cost for USA.
