Answer:
C. Bottling plant B (with 175,000 sports drinks per day), because the daily mean will be closer to 20 fluid ounces with more sports drinks in the sample.
Step-by-step explanation:
The general rule is that the larger the sample, the closer the sample mean will be to the population mean. This happens because the standard deviation of our sample is given by the following formula:
In which is the standard deviation of the mean volume of all of this type of sports drinks and is the size of the sample. So as increases, the less variation there will be, and the closer the sample mean will be to the population mean, that is, the closer the population mean is going to be closer to a mean volue of 20 fluid ounces.
So, the correct answer is:
C. Bottling plant B (with 175,000 sports drinks per day), because the daily mean will be closer to 20 fluid ounces with more sports drinks in the sample.
Answer:
Which number has a square root that is between 7 and 8?
NUMBER SQUARE SQUARE ROOT

7 49 2.646
8 64 2.828
9 81 3.000
Step-by-step explanation:
12 = 3 x 2"; 25 = 5?, and 35 = 5 × 7; therefore 3 x 2" x 5” x 7 = 210
