Answer:
Does this sample provide convincing evidence that the machine is working properly?
Yes.
Step-by-step explanation:
<u>Normal distribution test:</u>
Where,
Once the significance level was not given, It is usually taken an assumption of a 5% significance level.
Taking the significance level of 5%, which means a confidence level of 95%, we have a z-value of
Therefore, we <u>fail to reject the null</u>. It means that the hypothesis test is not statistically significant: the average length is not different from 1.5!
Answer:
C.
Step-by-step explanation:
11 is a prime number, meaning that its only factors are 1 and itself.
The answer is 308.0 grams
Explanation:
So we want to find how many grams are in 11 oz. The first step would be to find how many grams are in 1 oz, which would be about 28 grams. Now that we know there are about 28 grams in one ounce, we can solve for 11 ounces, by multiplying by 11. 28 x 11 = 308, therefore 11 oz = 308 g
Ok so the radius is half the diameter, and the diameter is half the circle. And the area is the space inside a circle. And pie is 3.14.
So if your radius is 10 then you will multiply 10 x 10 to get 100. Then multiply 100 x pie or 3.14 which you will get, 314cm². So your answer is 314cm²
The formula for an area of a circle is radius x radius = ?
Then multiply pie, 3.14 by your new radius x radius, and you got your answer.
False , it would be positive
