Answer:
D. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test
Step-by-step explanation:
Hello!
When planning what kind of hypothesis to use, you have to take into account any other studies that were made about that topic so that you can decide the orientation you will give them.
Normally, when there is no other information available to give an orientation to your experiment, the first step to take is to make a two-tailed test, for example, μ₁=μ₂ vs. μ₁≠μ₂, this way you can test whether there is any difference between the two stands. Only after having experimental evidence that there is any difference between the treatments is there any sense into testing which one is better than the other.
I hope you have a SUPER day!
Answer:
7.65 + 5p - (2.45 - 4p) =
7.65 + 5p - 2.45 + 4p =
5.20 + 9p <==
Step-by-step explanation:
hope dis helps mark me as brainliest pls!!!!!
The question states the interest is compounded annually. We have to use the given formula for this.
Principal Amount = P = $500
Interest Rate = r = 6% = 0.06
Time in years = t = 12
Compounding periods in a year = n = 1
Using the values in the given formula we get:
Thus, rounding to nearest cent the answer to this question is 1006.10
However, if you are also interested in finding the compound interest that is compounded continuously, use the following formula:
