Answer:
B)
No, we can only say there is 27% chance of seeing the observed effectiveness from natural sampling variation. There is no evidence the new formula is more effective but we cannot conclude equal effectiveness.
Step-by-step explanation:
Hello!
The company compared the old antiacid formula against the new one. The claim is that the new formula is more effective.
The hypotheses are
H₀: μ₁ ≤ μ₂
H₁: μ₁ > μ₂
Where the subfix 1 represents the new formula and the subfix 2 represents the old formula.
The statistical analysis threw a p-value of 0.27.
Remember if the p-value ≥ α, n the decision is to not reject the null hypothesis.
If p-value < α, the decision is to reject the null hypothesis.
Let's say α: 0.1 ⇒ you'd decide to not reject the null hypothesis.
Then there would not be enough evidence to say the new formula is better than the old one (μ₁ > μ₂) instead you'd conclude that the new formula is at most as effective as the old one (μ₁ ≤ μ₂). To know if it is equally effective as the old one or less effective a new test should be made.
In simple words, the p-value is the probability of obtaining the value of the statistic under the null hypothesis. In this case, there is a 27% of possibility of observing the effectiveness of the new antiacid formula from a sampling error than because the new antiacid formula is, in fact, effective.
I hope it helps!
<span>The question is which answer does show the standard form of the equation: 7-3(x-y)=-5x+2. To see that let's transform our equation into standard form. Standard form of a linear equation is: ax+by=c. So our equation is: 7-3x+3y=-5x+2. Now we put the unknowns on the left and the numbers on the right: -3x+5x+3y=2-7 and we get 2x+3y=-5. And we see that the correct answer is C. </span>
Answer:
2
Step-by-step explanation:
21/7=3 and 3 is half of 6 sooo with 1/3 the amount of cloth you would do 6/3 which is equivalent to 2
P - power measured in watts
E - voltage measured in volts
I - current measured in amperes
R - resistance measured in ohms
1. P = 2000 W, E = 200 V, R = ?
2. P = 0.35 W, E = 150 V, R = ?
