Answer:
Step-by-step explanation:
Let's assign each person a variable using the first letter of his/her name.
Then we get the following equations based on the information given:
Then we can use substitution:
Rearrange the second equation:
Multiple the equation by 3:
Combine the equations to solve for a single variable (L):
Then we have a new equation:
Use substitution to get the rest:
270,000 Because what you do is take the number and just look at the number behind the 6 and it was five so you rise.
Answer:
4 2/7
Hope this helps and have a nice day!!
Step-by-step explanation:
B. Yes, we are 99% confident that the population mean is within the interval.
C. Yes, 225 is below the interval minimum, so it is reasonable to conclude the average cholesterol level is greater than 225 mg/dl.
D. No. Increasing the sample size would decrease the margin of error, so the ends of the interval would move closer to the sample mean of 251.9. So the interval minimum would still be higher than 225.
