Answer:
a) 88% is a population characteristic.
Step-by-step explanation:
A population characteristic, also known as population parameter, describes a characteristic about the entire population of variables (usually numerically). Basically, it is a description (usually numerical) about a group of variables, obtained from the total population of such a variable.
WHILE
A statistic describes that same characteristic, only that it is obtained from a sample of variables taken from the population.
For the question above, a department notices that 88% of ALL their customers who use the store's credit plan pay their bills on time. It is evident that this is a population charasteristic, as it is obtained from examining the entire population of customers.
Hope this Helps!!!
So,
3/4=0.75
36/0.75=48
You need 48 paperclips to make it end to end.
The cost is:
48 x 0.02=0.96
The total cost is $0.96
Hope I helped!
