Answer:
A. On average the blood pressure levels before the stress reduction program were significantly higher than the systolic blood pressure levels after the stress reduction program, at 95% confidence level
Step-by-step explanation:
The confidence interval parameters is intended to detect if the new stress reduction program will lower the systolic blood pressure levels of employees
The difference between the the mean systolic blood pressure levels taken = The before systolic pressure - The after systolic blood pressure
The 95% confidence interval obtained = (5.6, 10.2)
Therefore, given that the values of the difference between the means are both positive, then there a difference as the confidence interval does not include zero (0), and at the 95% confidence level, the average systolic blood pressure levels before the stress reduction program are higher than the average systolic blood pressure levels after the program
D because it is talking about meters hope this helps
Answer:wo consecutive integers would be 13 and 14 because 13 x 13 = 169 and 14 x 14 = 196 and the inequality fits inbetween perfectly.
Step-by-step explanation:
A binomial distribution can only be used when there are 2 possible outcomes, no more, no less.
Looking at the situations given you are able to use a binomial distribution in 2 cases.
First is the quarter being flipped 3 times. There are only two possibilities (Heads or Tails).
Second is the 3 marbles being pulled out of the bag. There are only two types of marbles (Green and Blue).
Answer:
25 new cans
Step-by-step explanation:
Given that:
Number of aluminum cans needed to make a new can = 5
total number of aluminum cans = 125
Number of new cans that can be made :
Total number of aluminum cans / aluminum cans needed to make a new can
= 125 / 5
= 25 new cans
