- The null and alternative hypotheses would be given by H₀: μ = 7 and H₀: μ ≠ 7.
- The test statistic is equal to 1.198.
- The p-value is equal to 0.1262.
- In conclusion, yes the mean discharge differs from 7 fluid ounces.
<h3>What is a null hypothesis?</h3>
A null hypothesis (H₀) can be defined the opposite of an alternate hypothesis (H₁) and it asserts that two (2) possibilities are the same.
<h3>How to calculate value of the test statistic?</h3>
The test statistic can be calculated by using this formula:
Where:
- is the standard deviation.
- n is the number of hours.
For this clinical trial (study), we should use a t-test and the null and alternative hypotheses would be given by:
H₀: μ = 7
H₀: μ ≠ 7
Next, we would calculate the t-test as follows:
t = 0.08/0.0668
t = 1.198.
For the p-value, we have:
P-value = P(t < 1.198)
P-value = 0.1262.
Therefore, the p-value (0.1262) is greater than α = 0.10. Based on this, we should fail to reject the null hypothesis.
In conclusion, yes the mean discharge differs from 7 fluid ounces.

Answer:
2
Step-by-step explanation:
As she bought 4 times as many tiggerfish (y) as parrotfish (x) you need an equation that shows this relation:
y=4x.
So you can eliminate option 1.
Then you know that she bought, in total, 280 tropical fish. This means that all the tiggerfish and parrotfish together must sum 280:
x + y = 280.
The only option, between the remaining, with this equation is option 2.
So, option 2 is the correct.

Answer:
[See Below]
Step-by-step explanation:
✦ Divide by -2 on each side:
✧ -2 / -2 = Cancels Out
✧ -6 / -2 = 3
So x would be 3, -3.
- |x| Just means absolute value. Which in short just means if it's negative it becomes positive.
