Answer:
The population parameter is the average wait time for all the bank's customers.
Step-by-step explanation:
The population parameter is a numerical value that defines a specific characteristic of the population. For example, the population mean describes the average value of the population, the population variance describes the variance of the population and the population proportion describes the proportion of a certain variable in the population.
The sample statistic is a numerical value that defines a specific characteristic of the sample that is selected from the population. The examples of sample statistic are, sample mean, sample variance and sample proportion.
In this case it is provided that the bank manager wants to know the average amount of time customers of his bank have to wait in line.
The experiment involved, asking 300 customers about their average wait time at the bank.
So, the parameter under study is the mean time the customers have to wait at the bank.
Hence, the population parameter is the average wait time for all the bank's customers.
Answer:
<em><u>1) Sam's Club is better because the price for 10 cans at the village market would be $6.20 versus $4.70 from Sam's Club</u></em>
<em><u>2) 420 people with 210 per hour</u></em>
<em><u>3) It would be more beneficial to buy apples from the Quick Market considering the explanation below.</u></em>
<em><u>4) 396 quarts per hour and a daily rate of 792.</u></em>
Step-by-step explanation:
1) $3.10 x 2 = $6.20
2) 70 x 6 = 420
so, 210 per hour
3) $1.05 divided by 3 is $0.35 per apple at the Quick Market
$2.55 divided by 5 is $0.51 per apple at the Stop and Save.
4) take 330 and divide by 10 to get the amount per hour which is 33 quarts per hour.
330 + 33 + 33 = 396 for 12 hours
396 x 2 = 792 for one day.
