Answer:
The correct option is:
A. We are 95% confident that the interval from 55.4 seconds to 61.2 seconds actually does contain the true value of μ.
Explanation:
In statistics, confidence interval is the interval estimate about the population parameter of interest at certain level of confidence like 95%. A 95% confidence interval gives us a range of values that we can be 95% confident contains the true mean of the population.
Therefore, the option A is correct

Answer:
Answer 1)
Step-by-step explanation:
Starting with 1 + 3x = -x + 4, add x to both sides. Result: 1 + 4x = 4
Next, subtract 1 from both sides, obtaining 4x = 3.
Finally, divide both sides by 4: x = 3/4
This matches Answer 1).
