Answer:
33.3%
Step-by-step explanation:
1. Formula: difference/original
2. 120 - 80 = 40
3. 40/120
4. 1/3
5. 1/3 = 33.3%
32(87.5)
28.000
32-28=

Answer:
2x
Because 6 ÷ 3 = 2, so the answer is 2x
Using the interpretation of the confidence interval, it is found that the correct option is:
e) No, the confidence interval contains 0, so 0 is a plausible value for the true mean increase in number of miles driven on 25 gallons. An increase of 0 would indicate the gas mileage has not increased.
<h3>What is the interpretation of a x% confidence interval?</h3>
It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
In this question, the 99% confidence interval for the increase is of (-3.95, 64.35). It contains 0 and negative values, hence those are plausible values, and this is not enough evidence that the mean has increased, hence option e is correct.
