Answer:
We don't have sufficient evidence to support the claim
Step-by-step explanation:
Null hypothesis:
![H_0: p = 0.276](https://tex.z-dn.net/?f=H_0%3A%20p%20%3D%200.276)
Alternate hypothesis:
![H_1: p < 0.276](https://tex.z-dn.net/?f=H_1%3A%20p%20%3C%200.276)
The P-value is 0.3064
0.3064 probability of finding a sample proportion lower than the one found.
The p-value is higher than the significance level of 0.05, which means that there is no sufficient evidence to support the claim.
Answer:
B and D
Step-by-step explanation:
To find the percentage, you divide Martin's correct answers by the total number of questions, then multiply the result by 100.
To find the fraction, it's <em>correct answers/total questions</em>.
Answer:
2x+23
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the sum of all sides.
Therefore, in the given problem, the perimeter will be:
Perimeter = 21-x + 2x-3 + x+5
= 2x+23
The question is kind of all over the place. Can you clear it up a bit because it sound to me that all you have to do is simple addition and subtraction hun.
