Answer:
A
Step-by-step explanation:
As the sample size n increases, the sample mean (μy) becomes a more accurate estimate of the parametric mean, so the standard error of the mean becomes smaller. Therefore, the variance of y decreases and the distribution of y becomes highly concentrated around μy.
Answer:
the Lateral SA is 84
The total is 1092.
Step-by-step explanation:
You have to dive the x and the Y so R=7
Answer:
77% to the nearest whole number
Step-by-step explanation:
This is 60187 / 78250
= 0.7691
= 77%
Answer:
C) At most one sample is mutated
Step-by-step explanation:
If there are 15 samples, it means that 15 is the total (100%) of samples. Then, if we know that there is a chance that 3% are mutated, then we calculate the 3% of 15:
![Mutated= \frac{3. 15}{100} = 0.45](https://tex.z-dn.net/?f=Mutated%3D%20%5Cfrac%7B3.%2015%7D%7B100%7D%20%3D%200.45)
This means that at most one sample is mutated, as this result is not zero (we discard answer A), and 0.45 is not more than half of the samples.
