Answer:
Following are the answer to the given points.
Step-by-step explanation:
In point a:
The confidence interval for p is 95%
using formula:
![= \hat P - Z\times \sqrt{\frac{\hat P(1- \hat P)}{n}} < p < \hat P +Z \times \sqrt{\frac{\hat P(1- \hat P)}{n}}](https://tex.z-dn.net/?f=%3D%20%5Chat%20P%20-%20Z%5Ctimes%20%5Csqrt%7B%5Cfrac%7B%5Chat%20P%281-%20%5Chat%20P%29%7D%7Bn%7D%7D%20%3C%20p%20%3C%20%5Chat%20P%20%2BZ%20%5Ctimes%20%5Csqrt%7B%5Cfrac%7B%5Chat%20P%281-%20%5Chat%20P%29%7D%7Bn%7D%7D)
![= 0.28 - 1.96 \times \sqrt {\frac{(0.28 \times 0.72)}{350} } < p < 0.28 + 1.96 \times \sqrt{(\frac{0.28 \times 0.72)} { 350}}\\\\= 0.233 < p < 0.327](https://tex.z-dn.net/?f=%3D%200.28%20-%201.96%20%5Ctimes%20%5Csqrt%20%7B%5Cfrac%7B%280.28%20%5Ctimes%200.72%29%7D%7B350%7D%20%7D%20%3C%20p%20%3C%200.28%20%2B%201.96%20%5Ctimes%20%5Csqrt%7B%28%5Cfrac%7B0.28%20%5Ctimes%200.72%29%7D%20%7B%20350%7D%7D%5C%5C%5C%5C%3D%200.233%20%3C%20p%20%3C%200.327)
In point b:
Because 0.22 is not within the trust interval, they have enough proof of H0 at level 0.05.
In point c:
For the percentage for samples,
from ratio p
from sample ratio ![\hat{p}](https://tex.z-dn.net/?f=%5Chat%7Bp%7D)
In point d:
Standard deviation is used to measure the interval of confidence
Answer:
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
Red = 4
Blue = 6
Yellow = 2
Total = 4 + 6 + 2 = 12
Probability is that event divided by total event, so
Probability of Blue = 6/12 = 1/2
Since, we put the blue again back into the bag, so we still have same amount of each (this is with replacement, probability).
So, 2nd time:
Probability of Blue = 1/2 (same)
Now, we need to multiply these to get probability of blue IN A ROW:
1/2 * 1/2 = 1/4
