100+10+2
Step-by-step explanation:
Answer:
Hence, the minimum required sample size (n) should be = 1692
Step-by-step explanation:
Solution:-
- The estimation error, E = 2%
- The confidence level, CI = 90 %
- Since the proportion of the positive lab tests for prostate cancer are actually proven correct through subsequent biopsy are unknown we will assume the corresponding proportion to be p = 0.58
- The required sample size is a function of confidence value and error of estimation (E):
Where,
- The critical value of the confidence level = 90% would be:
significance level ( α ) = 1 - CI = 1 - 0.90 = 0.1
Z-critical = Z_α/2 = Z_0.05 = 1.645
- The required sample size (n) can be calculated:
![n = 0.5*( 1 - 0.5 ) * (\frac{1.645}{0.02})^2\\\\n = 1691.265](https://tex.z-dn.net/?f=n%20%3D%200.5%2A%28%201%20-%200.5%20%29%20%2A%20%28%5Cfrac%7B1.645%7D%7B0.02%7D%29%5E2%5C%5C%5C%5Cn%20%3D%201691.265)
- Hence, the minimum required sample size (n) should be = 1692
Answer: A. 2
Step-by-step explanation:
add all 5 numbers together to get 40 then add one of the answer choices to the total and divide each one by 6 until you get 7.
42/6=7
Answer:
No
Step-by-step explanation:
as X=-1. and y=5
according to this y<3x+8
which means 5< 3*-1 +8
5<-3+8
5<5
which is not true.. as 5=5
