Answer:
b.0.02
Step-by-step explanation:
As he defined the significance level in α=0.05, and this is a one-side test (as the claim is that the percentage is <em>higher, </em>not lower), any P-value below the significance level shows a significant effect and gives evidence to reject the null hypothesis.
The P-value represents the probability of having this sample statistic, given that the statement of the null hypothesis is true. Then, the lower the P-value, more evident is that the null hypothesis is not correct. This threshold value to reject (or not) the null hypothesis is the significance level.
a) As the significance level is 0.05, a P-value=0.07 would not be low enough to reject the null hypothesis.
c) The magnitude of a P-value has impact on whether he rejects or fails to reject the null hypothesis, as is the value that is compared to the significance level to reject or not the null hypothesis.
Only 3 of the resorts had a spa
Answer:
5unit
Step-by-step explanation: since area of rectangle = length*width
Here length is (x+2) and width is(2x+3)
(x+2)(2x+3)=91
On further solving
2x^2+75x-85=0
2x^2-10x+17x-85=0
2x(x-5)+17(x-5)=0
(2x+17)(x-5)=0
x=5unit
Answer:
X + Y <= 95.
Y >= 20+ X.
Step-by-step explanation:
It is given that section X and section Y can have hardly 95 questions.
Hence either both have them has total 95 questions or less than 95 questions.
If we take X as the number of questions section X has and Y as the number of questions section Y has then X + Y <= 95.
Also it is given that Y has at least more 20 more questions than Y has. Hence Y can have 20 more question than X has or more than 20 more question than X.
That is Y >= 20+ X.
As shown in the graph the line passing through (95, 0) and (0, 95) the arrows are towards the origin because the origin satisfies the equation.
In the other line the origin that is (0, 0) does not satisfy the equation. Hence the arrows will not be towards the origin.
